Christopher21 Jan 2011 22:22Hello everyone,
My girlfriend and I are finally starting the shell construction in March 2011.
We don’t have a basement, so we don’t have a lot of storage space.
Our house has about 185 m² (1990 sq ft) of living space, including storage rooms. We will have a large open living area with kitchen, living room, and dining room. This space is about 60 m² (645 sq ft).
In this room, there will be a wood-burning storage fireplace by the brand "Brunner," which the stove installer says can store heat for up to 8 hours. Since we can prepare our own firewood, we want to use this stove as much as possible for heating.
The living area on the ground floor also has very large window fronts. Additionally, both the ground floor and the upper floor have underfloor heating.
Now the question is how to install the heating system.
I was thinking about getting a condensing oil boiler with a solar system for domestic hot water, because it’s affordable. However, everyone around me says it’s not a good option.
I would like to hear your opinions on this.
At the moment, we really don’t know what the best solution is. Oh, and natural gas is not available here.
The only downside to oil heating that bothers me is that I need a whole room for the tanks and equipment.
I appreciate your help, thanks
Christopher

Hello,
Have a professional (not a heating installer or home seller) calculate the overall energy and cost balance, including hot water preparation.
Best regards

...In this room there is a wood storage stove chimney by the brand "Brunner," which according to the stove installer can store heat for 8 hours.
Christopher schrieb:Underfloor heating and storage stoves have poor operational compatibility because both respond slowly. Therefore, for the stove’s installation room, only an alternative, not parallel, operation would make sense. It would be different with radiators.
...Additionally, the ground floor and upper floor are equipped with underfloor heating.
Christopher schrieb:Cheap has never proven to be sustainably valuable in the long run. The fuel tank would be the least of the problems. Oil is by far the energy source facing the highest consumption competition. Choosing oil for a new build ignores the trends happening worldwide.
...I was thinking of installing a condensing oil boiler with a solar system for domestic hot water because it’s cheap.
Christopher schrieb:Since gas apparently is not an option here, a heat pump should be considered. Skip solar thermal systems, as they usually are not economical for a single-family home. Instead, invest the resources saved into better thermal insulation. With the reduced heating demand, consider an air source heat pump!

Hello Chr.,
In this room, there is a masonry heater with thermal storage from the brand "Brunner," which, according to the stove fitter, can store heat for up to 8 hours. Since we can prepare our own firewood, we plan to heat quite extensively with this stove.
You need to consider that in addition to the masonry heater with thermal storage, you must install a heating system capable of heating the entire building without the stove. What if you run out of wood or are unable to prepare any more?
Our living area on the ground floor also has very large window fronts. In addition, both the ground floor and the upper floor are equipped with underfloor heating.
Despite significant advances in recent years, windows remain the weakest building component. This means that according to the 2009 Energy Saving Ordinance, the heat loss through windows is still five times higher than through walls.
This results in a corresponding heating demand for the room, which, as already mentioned, must also be met by the heating system! At the same time, there must be a sufficiently large heat transfer surface!
Now the question arises as to how to install the heating system.
I was thinking about installing a condensing oil boiler with a solar system for domestic hot water, because it is affordable. However, everyone around us now says it is not a good choice.
Building and operating a house is not a project that can be planned with a horizon of just 5 or 10 years. You need to consider longer time periods! A good reference point is the service life of the different systems, apart from the available budget, of course.
What use is saving money in one area only to waste it on oil heating with additional losses (e.g., through the windows or chimney)? Underfloor heating is a good starting point for using various heating systems because it allows operation at low system temperatures. This reduces the required energy input.
Which energy source is the right one must be carefully weighed. Oil is not a suitable choice, first because of environmental concerns, the anticipated cost development, and supply security. Additional disadvantages include the space needed for the oil tank, maintenance costs, ordering requirements, and odor nuisance.
Heat pumps also require a room or an outdoor location on the property. This must be taken into account both for your own use and neighbors’ comfort, as the units produce noise and are visible.
Gas is also an option, even if no connection is currently available. It is possible to install a tank. Although no indoor storage space is needed, an appropriate outdoor location on the property is required. Regular refilling is also necessary. The cost development is expected to diverge from oil in the medium term because the linkage of gas prices to oil prices was annulled by the Federal Court of Justice (BGH).
Regarding supply security for gas, it is higher than for oil due to existing reserves. Additionally, biogas plays an increasingly important role and improves the supply security of this energy source.
If a gas supply connection is established on your street later by the utility, the tank can no longer be necessary!
Hope this helps you!
