Heating system too expensive can I get a better option??

horsenaughton

Currently deciding on heating system for a new build. Was planning on going with air to water heat pump, underfloor heating and heat recovery ventilation system with also a solid fuel stove. It's all coming in more than expected and just wondering what other options would people recommend

What did you get quoted and what size/type house?

House is about 2.9k square feet, it's a story and a half style and prices for the heating systems coming in around €36k that including domestic plumbing as well.

I got quoted 12k for air to water heat pump, under floor heating, pump and cylinder. Thats for 2100 sq ft bungalow.

Yours seems very expensive alright.

Well it's probably an OK quote. For the size house you have, I would estimate the breakdown to be along the lines of the following for a 2900sq ft house. That's a big house, so it will cost huge money for every aspect. Plus the cost of building is very high right now. Between 1200-1500euro per square meter.

The below would be including all materials and labour, and is only ballparks to help as a guide;

1.) HRV approx 6k
2.) UFH including manifolds, stats and heating controls, for 2900sq foot house approx 7k
3.) Air Source Heat pump for size house would be ballpark 10-12k
4.) Domestic internal plumbing for all internal pipework, Hot Water Cylinder, attic tank, hot and cold feeds to all bathrooms, kitchen, utility etc. Approx 8k -10k including materials

So for all that above I'd give a ballpark of 31k - 35k.

Hope this helps a bit.

Ask for a breakdown of the quotes recieved to help compare them.

Best of luck... :-)

not surprised by cost, but fascinated by how you reached the expected cost?

Very detailed. I still think its expensive though. The heat pump and cylinder I've been quoted is the largest they do so would certainly be suitable for a 2.9k sq ft house. Plus ufh and all controls, stats etc for 12k.

If you insulate the house more and get a really good airtight result you can reduce your heating system size. Way cheaper to run long term too. The "largest they do" part scares me. Sounds like they just picked the largest and not sure if it's sized correctly. I've a 2500sqf size house that's super insulated so have a tiny heat pump. A lot of super insulated houses (passive or near passive) don't put heating upstairs which is another saving. You also don't need individual room stats and all the controls either as it's all one comfortable zone with the heat recovery helping to disperse and regulate it. If you're just meeting insulating regs and haven't considered airtightness much then you'll need that big heating system and zoned stats.

Well they got the house plans to do the quote so I'd hope they used it. Quite a lot of large windows but house is specced for an A2 rating.

Hope..
Did you ask them to quote to do heat loss calculation?

In this context A2 means nothing unfortunately and won't help size your heating system

No I didn't. The pump isn't the biggest, I made a mistake with that, the hot water cylinder is the biggest. It's a 9kw pump.

A2W unit seems cheap?

Hi,

We are finding the same, our house is just over 3100 sq ft and the air to water heating systems are very expensive, I don't know if I can justify €20,000 or more for a heating system??

Is everyone spending that kind of money these days? Am seriously considering an oil boiler and seeing if PV panels will get us over the part L compliance requirements.

We want under floor heating downstairs with rads upstairs, will also have a wood burner in the sitting room.

I'd really like to hear other peoples experiences / opinions on this.

Thanks all

Build a passive certified house and use a compact heating system, e.g. the Nilan Compact P or Genvex 185 Combi system. This will provide approx 2kW heating through the ducting, which you can supplement with an electric towel rad or in duct booster depending on your requirements. The price for this system, which includes hot water tank, mvhr, ducting and installation would be in the region of ~€11k + VAT.
see case study:
https://passivehouseplus.ie/magazine/new-build/mallow-build-hits-passive-on-a-budget
The savings from the cheaper heating system will offset the passive certification costs. And it will be a better house.
