ᐅ Heating system design for a new build garage due to space constraints

Hello,

we are planning to build a single-family house next year and would like to install the heat pump heating system outside the utility room, as otherwise there is little space left for other equipment. The plan is to have a technical room in the adjacent garage (insulated and frost-free), about 4 meters (13 feet) away from the utility room.

Does anyone have experience with this? What should we consider, or would you completely advise against it?

What is the best way to route the pipes into the house?

.. and three meters from the property boundary. Building a garage on the boundary is then not possible, unless you plan it in a more complex way.

I would advise against it. You need to access the technical equipment more often than expected – even if just to check, adjust a setting, or read data. The new technology tends to make you quite curious. Although maybe this is resolved by associated apps? I don’t know, we don’t have that, but especially in the transition periods, we often make adjustments to the heating curve. Otherwise, the heating system (not a heat pump, but with an external sensor) just won’t get going properly: outside temperatures are acceptable, but it’s still cool inside. So I don’t see the point in always having to go into the cold garage to reach the utility room.

Thinking about it, the concept seems too simplistic. A house should be designed first, then the garage considered. Basically, you have to look at where the connections are and how they enter the house. Having the technical room “behind” the garage means the supply lines would be covered by the garage. So they have to enter through the front wall of the house and then be routed into the back of the garage, and then back into the house again. A lot of unnecessary piping. Then it’s also questionable whether the utility room might be better located on the upper floor.
Therefore, your question can’t be answered in general terms (I assumed a standard house with an attached garage), and the house design should be reviewed specifically to determine whether this makes sense or not.

A house has to be designed, after all.

Yes, the question seems a bit odd as long as the house is still being planned. If there isn’t enough space in the utility room, it simply needs to be designed larger.

Are you building an expensive garage—with insulation—for the car and the heating system? It might be better to have a standard garage and invest the saved money into the house including the technical equipment. Please remember that the garage or the installation location may need to meet strict fire protection requirements. Also, the district heating pipes required to connect to the house will incur additional costs.

Why not share your house plans (in a separate thread)?

Your idea about the plot makes no sense; it might only be acceptable in very exceptional cases.

You are planning a house with a gable roof on a very affordable plot in Lower Saxony. Based on your other information regarding income, an insulated garage does not seem feasible.

The question is: how large or small would the house have to be for your technical equipment or the utility room not to fit inside the house? I would start by examining this first. Often, the problem lies in the basic concept or a non-optimized house design.

Then show us the planned garage and the house on the plot.
