Advice needed on DIY central heating plan

[Justandtrace]

Hi all,
I'm hoping to install a simple central heating system in our new house being constructed in 2019. I want a 'bare bones' system to keep it as simple as possible. I will be running a single underfloor loop and 9 radiators from a woodfired boiler. I would appreciate any comments/advice on my plan below. Especially if some sort of expansion chamber is essential or optional for this system. Also, do I need to worry about internal pressure, and if so what is the simplest way of dealing with this? Appreciate your advice/comments.

Oh , if only it was that simple

Could I suggest you employ a professional to design this? We are a helpful forum but designing your heating system for free is probably stretching the goodwill season a little. We are happy to advise but there are too many safety feature and design considerations

Politely put

Well it’s a little rich

whats a wet back boiler? solid?

 

[Riley]

They said wood fired so who knows

Is this new house in the U.K?

The simplest way of dealing with this is to employ a Professional to design and install a suitable system.
This needs to comply with building regs and be fit for purpose.
A barebones system will not be adequate.

If only it was as simple as that JAT there a certain safety features that need installing with this type of system and as above you must comply with building regulations, you may by all means be able to do some work yourself but I would strongly advise you employ a HETAS engineer for the the wood burning boiler and flue system.

In theory your system will work. However because you are obviously not trained or conversant with current practice, legal obligations my list of faults with your scheme might take all Boxing Day to list. Your system is unsafe to the point of being dangerous. Get a professional in and have a good engineer install it. Your new house might be severely compromised if you do not. At best you will burn people’s feet with the uncontrolled unblended underfloor circuit, at worse it might well explode

I think it will be fine like that after all you have a PRV on the system & the pumps on the return, nothing else required.

Begs the question what will the rest of the house be like (at least until the winter comes).

It's another wind up.

Yer , it will be that last engineer with the long list of qualifications but no gas safe number .

What leads you to that conclusion? I see no reason to doubt that the OP came here in good faith wanting advice about something that turned out to be more complicated than they first thought.

 

[Riley]

Because if they were serious I’d imagine theyd have asked what was wrong with their design

whichever we have to take things as they present, and we all have the choice not to get involved, and if we stop some clown from tinkering with a potentially dangerous problem then I am happy ..centralheatking

The same as on many posts.

There's quite a few 'odd' posts that just don't seem right and many an op that don't arrive to the site in good faith.

Maybe its with being in this game so long you tend to spot a Muppet from a mile away.

That or the fact if somebody has drawn something out and then dropped it on the internet then you would assume that they had already been on the internet to glean information for a starting point.

IMHO the op's original post hints that they know more than they are letting on. Some sort of fishing expedition.
I think the internet term is TROLL.

You'll not stop clowns.
