Has anyone ever had downstairs heating hooked up to upstairs boiler? How much did it cost?

[SafetyBird]

So we are in the process of converting our Victorian mid-terrace back into one house after it was converted into two top and bottom flats about 20 years ago.

Each flat has its own boiler, and the bottom boiler is old and knackered so we've actually been using the upstairs kitchen temporarily as we can't afford to buy and install a brand new boiler for the downstairs kitchen/central heating right now.

Ideally we'd like the home to run on one boiler (as most houses do!) and we had a gas engineer vaguely tell us that hooking the downstairs heating up to the upstairs boiler would be a relatively easy job and a lot less expensive than installing a new boiler, but he didn't tell me by how much cheaper it would be!

Has anyone gone through a similar situation and can confirm if it indeed is significantly cheaper than just saving up for and installing a new boiler downstairs? It seems like a lot of work to me . I will of course be calling some gas engineers out for quotes but don't want to do that until I know vaguely a price I should be saving up for, ready to pay for the job.

Thanks!

it will certainly be cheaper but I can't see your pipework.

If you have a modern combi boiler it will be sized to give a decent hot water flow, something like 30kW power. Your house might only need 15kW to heat it. It's very rare for modern boilers to be short on power.

One thing that is essential if you are working on old systems, is to have it powerflushed to get most of the old rust and sediment out, before connecting it to your pump and boiler. And have a system filter fitted to catch the remaining grime (flushing can never get it all out).

If you have microbore pipes, consider sending them for scrap and replumbing in proper pipes.

The most important thing is to find a good plumber/heating installer, by personal recommendation, not by reading reviews which he might have written himself on a paid-for advertising website masquerading as honest customer comments.

Thanks, pigletjohn. It's a 28kW, I've just checked. I'm guessing you mean websites like mybuilder.com? Our neighbour seems pretty savvy and says he knows a lot of quality tradesmen so I will be asking him!

BOF is that you?!
