Put your Central Heating System question in here.

Just received a £24k quote to replace x2 IVT AX-09 ASHP's with some 8.5kw equivalent pumps.

These service a couple of heat exchangers for our pool. One of the ASHP's recently developed a power fault and apparently no more parts available and apparently I can't replace one, I have to replace both despite the other one working fine. They are 14 years old now, so hey ho.

We have a GSHP with a Vaillant back up gas boiler for central heating and hot water.

I'm sure the £24k quote is massively punching but if its not, surely I should just (if I can?) make use of our backup boiler, connect to the heat exchangers and heat the pool that way. Yes, not as efficient as some new heat pumps and not as "green" but by my simple man maths, still quids in doing that and paying more for heating the pool than £24k for a couple of replacement heat pumps?

Am I mad, stupid or both?

go for 24k of mcguivering stick the boiler on it ashp are the same as elec/battery cars, bite you in the donkey in the end money wise! i'd rather have 2x 30kw vaillant boilers that will last for 20years.

McAlpine do a strap on rubber boot for it.
