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

First of all, thank you for the input. I had the same idea. Our heat pump has a 185-liter (49-gallon) hot water storage tank, and we also have an additional 120-liter (32-gallon) buffer tank. The house is 170 square meters (1,830 square feet), with two showers and one bathtub.
Which systems have sufficient buffer storage?

Is it too big? 🙂 I have no idea… Let’s put it another way: it’s unnecessary. You can search the forum for buffer tanks and heat pumps. There are several threads on the topic.
Conclusion: unnecessary and, if anything, counterproductive. However, if it can’t be avoided, for example, install about 20 liters (5 gallons) on the return line.
P.S. How many people are you? For two people, 185 liters (49 gallons) of hot water is enough. With two kids, it’s not—meaning if one person fills the bathtub with 120 liters (32 gallons) of hot water and then the first one showers, the second showerer will get cold water...
I’m single with three girls, and after three showers there’s only water left at 25°C (77°F) for me. With a 300-liter (79-gallon) storage volume 😱
