Liking the series so far. I'm thinking about installing my own central heating in a house I'm purchasing. Would you say it's worth the cost saving over paying someone?
Glad you are liking the series so far. I bought a package deal from Mr Central Heating www.mrcentralheating.co.uk/package-deals/deals-by-type/heating-packs-with-plastic . They have many types and makes to choose from but I got the plastic deal with a worcester 25i combi boiler. I also added the magna clean filters so the overall cost for the whole system was around £1,600 + £300 for the plumber to install the boiler and run a new gas mains. I never got any quotes for a professional to install the whole system but looking online it could cost around £4000. Have you had any professional quotes to do yours?
@@LCWDIY Thanks, was looking at those deals myself. Have a tame plumber who would do the boiler for me so expecting a similar cost, also have to get gas put into the property. Haven't had a quote yet but I was thinking around the same price as you've found. 7 radiators and all piping etc.
I totally agree with you by installing the central heating system your self you cutting down the cost all you have to pay for the plumber to install the boiler enjoyed the video,
You can hang it and do the water connections BUT most plumbers will not install the gas or sign it off. It's much better to get all the pipes ready so your gas safe registered plumber can hang it and connect everything to the boiler. I paid £300 to have mine installed with a new gas pipe to the tap.
This is so interesting as always wondered how it was done. My Father just passed away and now I have the family home. It's been in the family since 1960. It's a 1930s house and no central heating.... So will need it installed. Can't wait to do the house up ! 😀
Those pushfits, the seal is down to the little rubber o-ring. As you are inserting the plastic pipe into the fitting, the sharp edges of the pipe itself and any grit and contamination particles present, will scour the plastic pipe and the rubber seal. And am not confident that the rubber o-ring itself will not dry up, become brittle and crumble over the years.
In your opinion is there any advantages from using plastic rather than copper? I'm about to have a 25 year old boiler replaced and for peace of mind I'm going to replace the central heating system pipework and some radiators. Can't decide on copper or plastic .
I'm no expert, just a DIYer. But in my opinion plastic is so much easier to run using the push fit connectors. I'm sure the plastic pipes and pushfits are guaranteed for 40-50 years (you'd need to check that). I just used copper tails to the rads because I think it looks nicer, although I left plastic tails to my bathroom radiator because I couldn't run the pipes straight, but it looks ok. Mines been installed for 3 years now and not had a single leak anywhere.
Alright mate ive just finished building my own house its around 15,000 square foot by any chance would you know how much it would cost to have central heating fitted through the whole house ?
No sorry I wouldn't know how much it would cost. I just worked out the size of the rooms and calculated the BTU for the size of the rads. Plenty of online calculators for that. Hope that helps.
It's all about the flow and balance. If all the pipe work was 15mm some of the rads wouldn't get the right amount of water, just like turning all the taps on in your house, the water flow would slow down on all of them (upstairs more than downstairs). Using 20mm allows a lot more water to flow around and can supply all the 15mm pipes with the same amount of water. Same goes with your taps, if you run 20mm pipe around and tee off to 15mm for each of your taps you could turn all of your taps on and not see much of a reduction in flow.
I insulated them all. As they're under a suspended floor with airflow from outside it stops any of the pipes cooling down and making the boiler work harder to reheat it.
Good luck with it. We got our house cheap as it needed a full renovation. No double glazing, no heating, rotten floors, lead pipes etc. It was still very daunting when we first got the keys and walked through the door though. Still the best thing we've even done but still have a lot of work to do.

Thank you it's definitely worth it and saves a lot of money

That's a perfect great and rock solid job. If I was plumbing my house I would make sure my plumber does it that way
Thank you
Good video, I am about to do the exact same project
Good luck!

The o rings in the pushfit fittings are exactly the same material as press fit fittings( epdm)eg no difference
That's why you need to use the inserts, stops any damage to the O ring.

@@LCWDIY thanks for the reply, I think I'll do as you have ,any pipes that can be see use copper and plastic elsewhere.
Rats bite through plastic
Very interesting
Can you not connect the plastic pipes to radiator vale or does it have to be copper ???
You can connect the plastic pipes to the rads. Some people say it just looks nicer having copper pipes showing
@@LCWDIY thank you for replying you legend 👍🏻

@@LCWDIY Ok mate worries 👍
Why you haven't gone for underfloor heating nowadays?
You put that tee on the wrong way 🤔 9min 10 sec
Forgive my ignorance but why do you sometimes use 15mm and then sometimes 20?
It's all about the flow and balance.

@@LCWDIY ah I see thanks for the informative reply
Alway
Always make sure u use copper washers on that pex pipe not brass
Thank you for the advice.
I’ve used Screwfix brass is that not good
Nice videos. Do you insulate the return pipe too, or just the hotter pipe?
I insulated them all. As they're under a suspended floor with airflow from outside it stops any of the pipes cooling down and making the boiler work harder to reheat it.
@@LCWDIY cheers, makes sense. Looking to buy my first place and tempted by a reasonably decent project. Your videos help make it less daunting.

Ah man, how are you working around all that clutter 😂
