ᐅ Distance between buffer tank and ground source heat pump

Hello everyone,

We are currently facing some issues with our installation. The plumbing company wants to install the proposed mechanical ventilation system with heat recovery in front of our meter cabinet, which would reduce the required 120cm (47 inches) of working clearance in front of the meter cabinet to only 95cm (37 inches). To avoid any risks, we want to fully comply with this regulation. This is now causing a minor space problem. It could be resolved if we don’t place the buffer tank directly next to the geothermal heat pump but instead move the heat pump out of the small technical room and install it in the utility room. The distance would then be about 4 meters (13 feet), or slightly less.

Is this possible?

Why am I asking here? Because we will be meeting with the tradespeople in the next few days, and I want to be prepared by then.

Many thanks for all your answers.

Best regards

But this doesn’t solve my space problem, does it?

A 300 L (79 gal) storage tank requires much less space than a combination of one 180 L (47 gal) and one 120 L (32 gal) tank. But I think by now you should have understood the main part of the solution (simply omitting the buffer tank)...

Are there geothermal heat pumps with a 300 liter (79 gallon) storage tank? I couldn't find any in my research.

Storage tank separate. Naturally, not as a combined unit.

Maybe a combined storage tank could be a solution?
We will get a Juratherm HDWPU 400 (300 liters (79 gallons) of domestic hot water + 100 liters (26 gallons) buffer tank).

Does anyone have experience with Juratherm?

Huh, now I’m lost. :-)

We planned for 180 plus 120. Why would I add a 300-liter (79-gallon) tank in addition to the 180? 🙂
