Flat Heating Installation - Gas or Electric

macman

Viessmann, Vaillant or Worcester Bosch are the 3 top Which? brands: your choice of RGI will normally be determined by the brand you choose, as the RGI will supply the boiler and most only fit one or two brands that they are accredited to. Get someone by local recommendation.

My tariff is 12p/kwh but the heatpump has a COP of around 2.5 which means for every 1kw in I get 2.5kwh out, therefore the heat it produces cost just 5p/kwh. Its even more efficient in the summer it uses between 1.5-2kwh a day to heat my hot water.

I was thinking that. 12p/kWh is quite cheap anyway. 
I should have thought about the heating situation a bit more before I bought.
No gas here as with many villages. Oil is popular but then there’s the zero carbon thing to consider.

The cost of sorting out the heating was factored in when I bought our place - the bonus being that I've also been getting Renewable Heat Incentive payments (I get the last one in January) totalling just over £5k which went a long way to paying towards the £7.5k cost of the heat pump. An oil boiler and tank would have cost around £4-4.5k at the time, dunno about LPG but I guess the boiler would have been around £2k plus all the tank stuff (base, piping etc).

The problem with tanks (both oil and LPG) is that you need enough space around them for both access and safety so they take up a lot of room and dont look everso pretty. My ASHP unit sits close to the wall on the drive, doesn't take up much room (I can still park two cars abreast by the side of it.
I also have the advantage of not have fleets of tankers coming to top it up - we've had a dozen or so up and down our road in the past couple of weeks as people are getting their tanks replenished for the winter - my neighbour has about four gas deliveries a year and he's only got a 2 bedroom semi.

Thanks. Forgot about the RHI. I’ll look into the requirements if I go for an air to air multi split ASHP.
Had oil at the last property and used a top up system with a local company.
Central air con is also a possibility, using the 100 x 200mm galvanised steel ducting that’s
connected to the warm air heater.
It’s not insulated but it could house some flexible ducting.

you dont get RHI with air to air, only air to water

Ok, thought so.  
Air to water would be a big install job.
With oil CH and electric rads off the agenda, it’s down to storage heaters vs ASHP air con. I think the latter may be easier than a complete E7 rewire.
