combining wood burner and boiler

[joe plumber]

hi, im after some on advice on using a conventional gas boiler and a wood burner for central heating. if any one could point me towwards some diagrams etc for the potential layout and controls that i would need to incorporate id be gratefull thanks

 

[migoplumber]

ask renewable, he is on the ball for this type of system.

the wood burner can only be used on an open vent system, if you are using a sealed heating system you require a dual coil cylinder. The wood burner MUST NOT be connected to an unvented cylinder. The reason is that the control thermostats cannot stop the wood burner when there is enough heat.

not that clued up on thsi - but isnt something called a neutraliser used ? would like to know more myself

There is, try googling "Dunsley" I have fitted one or two but I think there must be a better way!!!

 

[peteh20]

you can use a dunsley neutraliser or google h2 panal have fitted both and both have there advantages. There is also a thermal store on the market but its 1000 litre capacity and definatly specialised bit of kit

You can connect the wood burner up to a pressurised cylinder although the heating side needs to be vented, gledhill do a cylinder they specify for this very type of heating.

This is exactly the system I have at home wood, solar, oil, we use the oil in the mornings and when we can't be bothered wood evenings and solar in the summer


Its quite simple as it's only another heat source I have used a 20kw log burners with an adjustable baffles, to control the heat (to a point) use a large cylinder

I have a 300 litre pressurise cylinder up in the loft
Gravity hw and pumped central heating with a pipe stat on the return to the burner

I dont think so! You may have a thermal store with mains hot water but its a vented cylinder. hopefully

 

[migoplumber]

if you do have i hope you have an air raid shelter in the basement !!

 

[pureplumber]

As I said in the first paragraph the burner is open vented.
Some people like to make out this job is rocket science

Not being funny but have you any qualifications to make statments like that!

Just checked your web site and I was right!

What you have is a gledhill torrent solar HE .... a thermal store which is not an unvented cylinder. Quite acceptable for the use solar/solid fuel/gas or oil.
If you dont understand what you have in your own home please dont try to put down plumbers who are far more qualified and experienced than yourself. You have been giving out infomation that contradicts building regs part G3. Law of the land.
If you dont know ask

Just to reiterate the above is not correct and is a dangerous statement to follow,possibly arising from a misunderstanding of the equipment installed in his own home
Unvented cylinders should not be connected to a uncontrollable heat source,for obvious reasons and all works/connections on a unvented cylinder should be carried out by a fully qualified person in that field

 

[pureplumber]

You are more qualified than who?
As I have said the boiler is open vented but if you choose to sit on your lofty holier than thou attitude thats where you will stay in your own little world thanks for looking at our web site and deciding for our site you where right give yourself a huge pat on the back it must be great being you!

Biomass boilers with all safety controls in place and on certain systems can be installed with unvented cylinders.

But OP asked about a wood burning stove/boiler which as I would hope you know is an uncontrolled heat source and you can not inform people it is ok to install with an unvented cylinder.
You seem to have a fundamental lack of understanding between unvented cylinders and thermal stores.

But what do I know?
I'm only a Plumber.

STOP it now girls !!

Sorry Migo

[joe plumber]

hi thanks for some of the help i appreciate it cant be used with an unvented cylinder i wasn't planning on using one to be fair. i appreciate a thermal store but am i right in thinking these cost alot of money ?? can i just use a twin coil VENTED cylinder ?? how do i go about linking my woodstove to work with existing heating circuit.also maybe a silly question but the pipework for the heating circuit is mostly hep under the floor will this be suitable witha wood burner

 

[ecowarm]

I think your best option would be a thermal store and run the heating from the lower (cooler) part of the store.

Thermal stores are not that expensive

 

[joe plumber]

ok thanks that sounds prmouising i will do soe of my own research! had a look on the h2 panel website it looks like a good bitof kit pricey though?? some one said thay had fitted one?? any opinions on it?

 

[Toddyplumb]

You cannot use Hep2o for gravity circuits from solid fuel stove. For the heating if pumped you should look at the Hep spec tables for Temp and pressure.
If it was me I would use copper

 

[joe plumber]

yea i'm aware you couldnt use it on the gravity from the wodburner in an ideal world i'd use copper everywhere howeve i need to work with whats already installed.

really appreciate the help guys i have a clear picture in myhead now

looking to do my hetas in jan anyone donethe course
