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
K

Huh, now I'm lost. 🙂

We planned 180 plus 120. Why would I now add a 300-liter (80-gallon) tank alongside the 180? 🙂
I meant instead of 180 + 120 liters, just ONE tank that is basically 2-in-1: more hot water (300 liters / 80 gallons) and a slightly smaller buffer tank (100 liters / 26 gallons).

Again: Nobody really needs a buffer tank, especially not for heating or underfloor heating systems, and the size of the hot water storage tank depends on the family size and individual water consumption…
