Heating with Ice Sun and Water

Ice Engergiequelle as the future for your house or commercial firstonce sounds paradoxical.With a Eisheizung consisting of an ice storage and heat pump, it is possible to heat up .Here you will find information and video posts on the heat with ice .

When freezing of water releases energy, the so-called crystallization energy. This energy we can use. When freezing of 1 kg of water at 0 ° C is as much energy as during cooling of 1 kg of water at 80 ° C to 0 ° C. The energy that is released during the freezing of water can be harnessed with a heat pump.

Heating with Ice ( The latest innovation from Germany)

The energy that comes in from the cold. How the application of a natural law is revolutionizing the climatization of buildings.

0° water and 0° ice.

With regard to energy, as different as day and night. To make ice melt, you need heat. Conversely, when water is turned into ice, the same quantity of heat is released. Nature is that simple.
The phenomenon of heat of crystallization, i.e. heat that arises during the transition from 0° cold water to 0° cold ice, is nothing new. For the first time, SolarEis has made this phenomenon technically manageable on a large scale.

By exploiting the heat of crystallization, the SolarEis system opens up and stores yet another regenerative source of energy alongside solar power. This is how the system revolutionizes the climatization of buildings: heating and cooling become far more effective, economical, and environmentally compatible.

Mother nature is full of energy.
In view of climate change, renewable forms of energy that do not cause any CO2 emissions are among the great issues of the future. SolarEis exploits no fewer than five natural regenerative sources of energy: sun, air, geothermal heat, water, and ice.

The power of the sun is an important provider of energy for the SolarEis system. In our latitudes, the sun delivers an average of 1000 kWh per square meter.

Heated air stores solar energy. Exploiting this is only one of the innovative ideas from SolarEis.

Water is one of the most efficient storage media for thermal energy that exists. Even water that is subjectively
felt to be cold still retains heat that can be utilized.

Geothermal heat from the upper layers of the earth supports the SolarEis system. Here, the constant temperature between 8° and 10° is fully exploited.

Heat of crystallization is released during the phase transition from 0° cold water to 0° cold ice. The energy corresponds approximately to the quantity of energy required to heat water from 0° to 80°. In the innovative SolarEis system cycle, the sun, air, geothermal heat, water, and ice not only generate heat for heating and for
hot water supplies but also ensure cooling in summer. A more effective and environmentally compatible climatization of buildings is inconceivable.

SolarEis is full of innovative ideas.

In the SolarEis system, the above-average amounts of energy in summer are not
only used immediately but are also stored for the coming heating period. This means
that solar energy is also used with the highest efficiency in the transition period
and in winter.

SolarEis exploits heat in the air as an additional source of energy. This is achieved
by deploying a combined extracting solar-air collector that also remains operational
when the sky is cloudy or at night. This is fitted onto the roof of a house or garage.

As SolarEis stores the heat in the most economical range, namely at low temperatures,
the geothermal heat that is virtually constant at 8 to 10° C over the year makes
an effective contribution. Cost-intensive insulation measures are not necessary.

Water becomes particularly economical as a storage medium when heat is stored
in the low temperature range. In the case of SolarEis, this is 0 to 10° C. The thermal
energy available at these temperatures and above all the heat of crystallization that
arises during freezing are exploited.

Exploitation of the heat of crystallization that arises during the transition from water
to ice is the core innovative idea behind SolarEis. The heat that is released is used
for heating; in summer, the ice that is created is used for cooling.
Heating and cooling with the power
of nature.
The cycle of the seasons regulates the effective use of our five regenerative sources of energy. In summer, surplus heat is placed in intermediate storage in the underground SolarEis tank – in the most effective way imaginable: with zero loss in water at a low temperature level. The heat stored in the ground is sufficient;
complex and cost-intensive heat insulation is not required. At the start of the cold season, the water in the SolarEis tank is continuously cooled to freezing point in a controlled process. The special feature: during the transition from 0° cold water to 0° cold ice, an enormous quantity of heat is released – the socalled
heat of crystallization. As soon as a fully automatic controller detects that the solar energy is no longer sufficient to cover the heating and hot water requirements, the system draws additional energy from the SolarEis tank. At the end of the heating period, the opposite process commences. The water in the SolarEis tank has been transformed into ice in a controlled process. To the same extent that thermal energy is once again stored, the cold that is released can be used for cooling in the hot season. For the first time, the SolarEis system has made the physical phenomenon of crystallization energy technically manageable
on a large scale. It is the utilization of this additional source of energy that makes the system so unique and economical.

1. SolarEis collector

It absorbs the heat of the sun and of the heated ambient air, even if the sky is cloudy or the solar radiation is diffuse. This makes its energy yield higher than that of classical solar systems. Surpluses in summer are stored in the SolarEis tank (3).

2. Hot water tank
It stores the heat required for heating
and hot water. When the sun is shining,
it draws its energy from the SolarEis
collector (1); the rest of the time it draws
its energy from the SolarEis tank (3) and
the heat pump (4).
3. SolarEis tank
The innovative centerpiece of the Solar-
Eis system. In the hot season, surplus
solar energy is stored here in large-volume
quantities of water at a low temperature
level. The surrounding geothermal
heat enables storage over longer periods
and without complicated and costly insulation.
At the start of the cold season,
the heat is drawn from the underground
tank and fed via the heat pump (4) to the
hot water tank (2) and the heating system.
During the controlled phase transition
from water to ice, large quantities of
crystallization energy are released. In the
following summer, the ice can be used
for cooling free of charge.
4. Heat pump
It draws heat from the underground SolarEis
tank (3) and feeds it to the hot water
tank (2) and heating system. At the
same time, it supplies the rooms with
5. SolarEis control system
This regulates the overall system and
decides in particular whether the heat
of the SolarEis collector (1) is used for
hot water or is fed into the SolarEis tank
As long ago as 2006, SolarEis received the Innovation Award
of the German Gas Industry and in 2010 it won the Innovation
Award of the Federation of German Chambers of Commerce
and Industry. These awards went to a heating system that combines
environmental compatibility with low operating costs and
the highest level of convenience.
Up to five regenerative sources of energy feed the system, thus
making it one of the most environmentally sound and efficient
heating systems available. Compared to other systems, the investment
costs pay off after only a few years. Cost factors such
as a gas connection, oil tank, or the annual visit from the chimney
sweep become unnecessary.
SolarEis is good for the environment
and saves you money.
SolarEis – an award-winning system

Whereas geothermal systems can
suffer from drops in power output due
to the ground cooling down or freezing,
SolarEis delivers reliable results over
the entire year.
SolarEis is fascinating and environmentally
friendly at the same time. The
integration of up to five regenerative
sources of energy achieves optimal
efficiency. The storage of energy in the
low-cost medium of water without the
high overhead for insulation measures
enhances the effectiveness of the
Economic efficiency
The University of Biberach determined
that SolarEis generates 5.46 units of
energy free of charge from regenerative
sources of energy. This means that
– with comparable investment costs –
SolarEis is superior to all other systems
with regard to economic efficiency. The
SolarEis system is above all independent
of rising energy costs and delivers
the cooling factor in summer free of
A SolarEis tank does not endanger the
ground water; it can even be used in
ground water protection zones. Drilling
through anhydride, for example, a
known source of danger, becomes unnecessary,
which means approval from
the relevant water authorities is not required.
Another indication of the safety
quality of our system is the fact that we
grant a 30-year warranty with regard to
the leak-tightness of the SolarEis tank
for detached houses.
Without approval from
water authorities
Compared to other heating systems, SolarEis convinces with
its effectiveness, reliability, and environmental compatibility, as
well as with attractive investment and operating costs.
For some time now, commercial properties have been heated
and air-conditioned economically with SolarEis systems.
Ice tanks with a volume of more than 1,000 m3 are used here.
Since 2009, the SolarEis system has also been available for
new buildings or for the modernization of privately used living
accommodation. The SE 12 system developed for this purpose
received the Innovation Award of the Federation of German
Chambers of Commerce and Industry and ‚Impulse‘ magazine
in the year 2010. We grant a warranty of 30 years with regard to
the leak-tightness of the SolarEis tank in this system.

Today we did our first (Blower Door Test) Air leak test and passed with 0.27 ACH@50

0.27 ACH@50 Air leak test for Reno Coach Passive House Toronto

Wow First test and passed with over 50% better than the German  Passive House standard of 0.60 ACH@50
Our reading came in at 0.27 ACH @ 50. On the other side with positive pressure we came in at 0.07 ACH@50 Which tells us some of the tapped Joints where  opening up under negative pressure.
We sure have to give the German Passive house windows and Doors a lot of credit and the detailed work by our crew for insulating ( by Foam Works )  and air sealing all the joints.

Why we need a Blower door test?

Are Blower-Door Regulations Too Big a Burden?
An owner/builder struggles with the uncertain cost of airtightness testing

In some states, blower-door testing is mandatory
As energy codes develop tougher rules for air tightness in new construction, an owner/builder worries that multiple tests could impose a heavy financial burden.

Building tight houses is a fundamental step toward energy efficiency, and figuring out how well you’ve done is actually pretty simple.
Air leakage is calculated with a blower-door test. A technician depressurizes the house with a blower sealed into a doorway and measures how much air can pass through the building envelope.
The result is typically described either as air changes per hour at a pressure difference of 50 pascals — ach50 in industry lingo — or cubic feet per minute (CFM) @ 50 pascals. Either way, air leakage becomes a known value. If the house is too leaky, the builder can take corrective steps to tighten it up.
The process isn’t intended to be onerous. But Frank Keeler, who wants to build his own house in Washington state, has concluded that the required blower-door test is enough for him to abandon the idea of building altogether, as he explains in a recent Q&A post at GreenBuildingAdvisor.
“We are building a new home ourselves,” he writes, “and are looking for a checklist to help us prepare for the blower door test.”
Requirements for the test in Washington state have only recently been enforced, he adds, and it’s proving hard to get solid advice. Moreover, costs can range from $75 an hour to thousands of dollars, depending on where you live, and there’s no telling how many tests he’ll need to pay for.




His dilemma is the subject of this week’s Q&A Spotlight.

Where to get help
General information about blower-door testing is available online. Resources include an article by GBA senior editor Martin Holladay explaining the protocol for conducting a blower-door test and the locations of common air leaks.
Another, pointed out by Robert Post, is the green-building web site Oikos, which publishes a guide to air sealing that covers everything from doors and windows to recessed lights and attic hatches.
As to the prospect of paying through the nose for the tests, David Meiland suggests Keeler contact the Washington State University Extension Energy Program. It recently handed out 40 grants statewide for the purchase of blower-door kits to relieve backlogs, and the office should be able to offer a referral.
“Anyone trying to charge thousands is way out of reach,” Meiland says. “It takes perhaps an hour to load in, set up, run the test, pack up, and leave. It takes significantly more time than that once you take into account travel time, finding leaks for unhappy failing owners and builders, follow-up phone calls from those same unhappy folks who want help, billing and getting paid, and so on,” he adds.
For builder/owners like Keeler, the situation can look intimidating. “Our government is besieged by people upset with their polices, and this is a good example,” he writes. “They are so concerned with the technical details and what constitutes the test they completely ignore the people on the ground doing the work or testing. The IRC 2009 standards are in some cases arbitrary and confusing so people just throw up their hands in frustration.”
He would like to see the state require a certified technician conduct the test, establish a maximum cost, and require that the customer get a detailed check-off list in the event the house fails to pass. “This is another government zero-sum game,” he adds. “The cost in money, gas used, and time will never pay for the gains you get from this procedure. Like it or not, people still open windows.”

What to shoot for
To win certification under Passive House requirements, a house must be very tight indeed: the threshold is 0.6 ach50. Very few new houses meet that standard.
But Meiland thinks 5 ach50 is “quite easy” to meet, and that 2 ach50 to 3 ach50 is a reasonable goal. “It seems like right now we're in a sort of transitional period as energy code brings blower-door testing to the masses,” he says. “Once you have gone through the process of airtight details once, it's a lot easier the second time, and more and more builders will either own the test equipment or have a sub close by who does, so all of this drama will probably fade away and people will know how to meet the targets without so much hand-wringing.”
But to Keeler, not knowing how many tests he’d have to pay for, plus the labor and materials involved in sealing leaks, seems like too much. “The uncertainty of cost is just too great,” he says. He and his wife have decided not to apply for a building permit.
“The project is scary enough without the thought of spending weeks and thousands of dollars on test after test. It's all too much,” he writes. “This to me signals the end to the owner/builder because of the inability to budget for ramifications of unforeseen number of tests.”
Meiland thinks Keeler's description makes the situation sound worse than it really is, and fellow owner/builder Holladay adds this: “If your budget isn't quite large enough for a home-building project, that's perfectly understandable. But the problem isn't the blower-door test. After all, the blower-door test is designed to help you lower costs, because the test will result in an energy-efficient building that will save you money for years.
“Perhaps you can design and build a smaller, more affordable house. If you do, be sure to build it tight! You'll be glad you did.”

Our expert’s opinion
GBA technical director Peter Yost had these comments:
Don’t give up yet! You can do this!
First, start with this free checklist and guidance: EPA Thermal Bypass Checklist Guide.
Finally, consider this low-tech approach: Buy a really high-quality and powerful window fan, the kind that fits right into a window opening. The one I have was made by Lakewood Engineering in Chicago (no longer available) but this whole house fan made by Air King will work just as well.
After you have air-sealed (and before you have insulated, unless your insulation is an airtight type such as spray foam) while the framing cavities are all open, run this window fan (and any other exhaust fans — for example, bath fans — that you may have installed and working in the home). The fan should be blowing out the window, not in.
I will bet that the combined depressurization force of these fans will approach 30 Pascals, which would be enough for you to go around your home with a smoke stick, a Wizard stick, a stick of incense, or even just a bunch of matches, to find any air leaks left at this stage of your work. (When you see the smoke waver, you've pinpointed a source of infiltration.)
If you use the Thermal Bypass Checklist and the window fan, I bet that you can get your new home down to less than 4 ach50, and then some — probably more like 2 ach50.
The official blower-door test quantifies your air leakage, but any force that significantly depressurizes your home can qualitatively identify the location of any air leaks you have missed while following the thermal bypass checklist.
This way you pay for one blower-door test at the end of your air-sealing work, and you end up with a great way to cool your house (the whole-house window fan) and a really fun toy (the Wizard Stick).
