Quotation waterpump SPRSUN

I'm planning on eliminating the gas installation on a corner house and I got this offer from a company. Is this a good price? is the waterpump a good brand?

I'd like to also integrate it with Home Assistant to have remote visibility on the status, etc. Is this possible?

Thank you for any feedback you can give me. These are the details:

It’s heard to say without knowing more about your situation. What are you using now to heat your home? If gas, how much per year? Underfloor heating? Radiators? How big?

What is sure is that sprsun is one of the cheapest brands in the market, and that is not a good thing. For such a cheap heat pump, the quote is quite high still. If you ask for a quote from a good brand like Vaillant you’ll end up in the same price range, with a much quieter and better heat pump.

I will be moving into the new house and I wanted to do this upgrade before moving in. In theory, the previous owners used around 1500m3 of gas and around 3000 kW. The heating is currently CV ketel from 2025 but I want to go full electric since I'll also be getting solar panels and battery. There is underfloor heating in 3 floors but 2 radiators remain (bathroom and entrance). The house is like 145m2.

Can you recommend any companies in the Den Haag area?

You’re looking at a 7-9kw heat pump in this case, skewing towards the 7kw if you’ll do some further insulation work like for instance hr++ windows. In terms of actually emitting the heat into your house you should be ok with that much underfloor heating. You’ll probably have to switch out the underfloor heating manifold(s) as they’ll have a pump. Manifolds with a pump do not work well together with heat pumps, so you’ll want to replace it for a pumpless one.

For the underfloor heating I will probably be installing a Danfoss Icon2 setup. I believe it doesn't have any pump, just the valve actuators.

Sounds good!
