Ugrading boiler, idea of costs?

waynedance

I have a house built in the 70's, I have a boiler (prima f30) in the kitchen with timer, tank in the loft and a hot water tank in the upstairs cupboard.

I believe you have to fit condensing boilers now, does this mean i need no tank in loft or cupboard?
Are my existing radiators till ok to use?
What are the likely costs of upgrading?

cheers.

Yes, with a very few exceptions, you now have to fit Condensing boilers.

Condensing boilers are more efficient than the older type such as your Prima.

However these do not have to be Combination boilers so you can retain the indirect system with a tank in the roof for your central heating.

Combination boilers supply both hot water for the central heating and instant hot water for the domestic taps.

You are free to choose a normal Condensing boiler for the ch only and heat your hot water in an indirect cylinder as in your current system.

Maybe you can sell me your Prima for spares as per my thread.

Avoriaz

You can use your existing radiators, pump etc if they are in good condition and just replace the boiler.

Boilers cost from about £500 upwards plus the cost of installation which varies enormously.

Cheers info, so i could get a new boiler and keep the tanks. So to loose the tanks i need to have a combi boiler, i suppose this would be a costly way to go but i guess you would save gas having hot water on demand.

Good evening: Take a look at similar threads on this forum and 'Is this Quote Fair' to get an idea of costs, what is possible etc.

Avoriaz is quite right. By law you now have to fit a condensing boiler, be it heat only, or combi. You require heat only at the moment. If your system is gravity hot water and pumped ch, when a new boiler is fitted, you will have to have a conversion to fully pumped, which can be pricey, although you may well have a fully pumped system already - do you have a 3 port valve in the system?

A decent A rated boiler will cost about £650 + maybe £30 for a standard horizontal flue kit. Bear in mind, if you go combi, it is quite likely your gas supply will need to be uprated.

Can you give us any more detail on your existing system??

I have no idea what system. I have a boiler with a duel timer in the kitchen, a cold water tank in the loft, a hot water tank with a pump (newish pump) in the bedroom cupboard & a thermostat in the bedroom.

The boiler did stop working a few years back (no heating or hot water) and it was the pump next to the hot water tank.

Sorry can not be more helpful, just wanted a ball park figure without getting someone out to quote me.

So what do you think I have?

You have no idea what boiler you have? how is this possible?

It sounds like you have a fully pumped system.
I used to prefer indirect systems like yours, as the boilers were simpler and more reliable. They are still simpler than a combi, but now tend to incorporate modulating gas valves and printed circuit boards, so not as simple as they were!
Both systems have their up’s and downs. Indirect is better if you have more than one bathroom. If space is a premium, go combi - you will lose the loft tanks and the cylinder.

Costs…….(app)

A rated combi £650
Flue Kit £30
Pipe & sundries £100
Labour £ depends who does it, but allow a couple of days

Whichever route you choose, it’s likely that your gas supply will need to be uprated. Allow around £100 materials and a days labour.

Hope this helps.

Nah, skimmed over it & went straight to the end
