Common situation

A home on storage heaters: how to heat, cool and run hot water

One of the strongest cases for air-to-air: whole-home heating and cooling from the same equipment, keeping the immersion cylinder for hot water.

Best fit for this home

Fixed AC throughout, with a separate hot-water cylinder

Air-to-air heat pumps heat and cool every room; hot water comes from a cylinder of its own

Strong fit. No close second, and nothing important left unknown.

This is the best fit because you're after better comfort throughout the home, your home is heated by electricity today and you're open to replacing everything.

Cost

££

A mid-range project: more equipment, more labour, more making good.

The air-conditioning part — 5 indoor units, 1 outdoor — estimates at £4,800–£10,500 installed.

Cost tiers are Airva's own assessment of these routes relative to each other, not a quotation. We don't publish a whole-home price range — an installer survey sets the price.

Why this won: On balance, this does more of what you asked for than Ducted AC + cylinder.

  • Improves comfort across the home, not one room
  • Far cheaper to run than electric panel or storage heating
  • A complete, coherent replacement
  • Scales to cooling across the home

The alternatives, and how they differ

Good alternative

Concealed ducted heating and cooling, with a separate cylinder

  • ↔ Heats through concealed ducts instead
  • ↔ More building work
  • ↔ Costs more

What would change this plan?

  • If you wanted to keep your heating exactly as it is → Keep your existing heating and add fixed AC
  • If nothing but a grille could show → Concealed ducted heating and cooling, with a separate cylinder

Could a grant apply?

Requires installer confirmation. This plan replaces your main heating, so a grant may be in play. Three quick questions decide the position.

  • Which nation the property is in
  • Whether you own it
  • Whether it is a new build
The eligibility rules, with the official sources →

What an installer must confirm

  • Whether the electrical supply and consumer unit can carry the new load
  • That the installer is MCS-certified, if you want to pursue a grant
  • A whole-home survey: heat loss room by room, pipe runs and equipment positions
  • Whether the loft or ceiling void is usable for equipment and ducts
  • Whether a compatible hot-water package is available for the system and your demand

This plan replaces your main heating, so government support may be in play. It is claimed by an MCS-certified installer, never by you directly.

Why not the others

  • Heat pump + radiators, Heat pump + radiators + AC, Heat pump + fan coils — there are no radiators or underfloor pipes to feed, and installing them isn't on the table.
