Heat pump grants

[Stinsy]

I'm thinking of getting a 3.5kW or 5kW air-to-air for my upstairs landing to do some of the heavy lifting during the 2030-0030 octopus cheap period. Works out way cheaper than gas if the electric is 5p and the gas is 4p per kWh what with the CoP of 3-4. Not-so-great on 35p/kWh electric though.

The problem is: who knows what will happen to the comparative prices of gas and electric or even the availability of super-cheap ToU electric. I'm not ready to bin off the gas boiler just yet, but neither would I be in a rush to buy a new one if mine went kaput.

Of a similar thinking here too. I can't see a time where I'd want to fully shut off my gas supply. I like having the choice.
Also very appealing in that if my insulation measures and the CoP of the unit make it effective on my as is CH system then I'd not need the gas on for very long. No different from the large scale gas turbines spooling up to supply grid power demand yet at a micro level?

I have my concerns that the £5k grant will be " UP TO" and be limited to a % of the total or just for the HP itself.

My other concern is that if it is MCS fitted it will cost too much and be too big because of the SAP calcs being done on every living room being at 21C and the emitters and insulation being that to achieve a min COP of 3 ? How many installers follow the rules i have no idea but not many i suspect for various reasons.

Too small a HP, too small enmiters, badly set up- take the money and run and then go bust. Sound famaliar -here we go again.

I’ve heard a lot of stories of undersized heat pumps being fitted, they often come with built in resistive heaters intended to augment the heat pump in exceptionally cold weather but instead run continuously.
