Heat pump ready cylinders, are Vaillants small coil good enough?

Thanks @Bramco. Might look into Cool Energy then as the £7.5k grant is quite a disincentive to self-install if it cannot be claimed (with a self-install). My understanding is the grant is only available with an MCS approved install. Seems there is a firm that will do the MCS paperwork for a self-install for about £1.5k so that could be an alternative option.

@MoDo  That seems lower than the uplifts I seemed to be getting on quotes, although it's hard to work out from a quote. Maybe a way forward.  Wonder if there's someone that would do the MCS for a battery install - a lot simpler as there's no heat loss calcs. Can you share the name of the folks that would do it for an ASHP?

I saw it here (another thread).

Downside is the £1.5k only gets you the grant, no physical installation work. Though as you say, it seems majority if not all MCS installers are whacking on significantly more than £1.5k with grant funded installations.

I’ve got the 1m2 vaillant cylinder… 9kW heat pump with a pwm pump driving into it. Works perfectly and recovers fast.

do you mean a 1m2 primary heating coil? with a pump to increase the flow through coil? what l/m pump did you decide on
