Building regs approval or not?

[Selfbuilder3]

Hello,
I'm thinking of fitting a woodburning stove with back boilder in a new build.
The system would provide hot water for bathing/cooking & central heating using a twin coil hot water (one coil for solar & the other coil for log stove).

Question 1 -
Does such a system need to be fitted by a qualified plumber?
Or can I as long as the system is correct (I intend to copy a friends system) DIY fit the system?.

Question 2
As new build, building regs would inspect relevant work but like part p for electrial instilation do i need a simular certificate to keep building regs happy?

I be be grateful for any relevant information.

David

Pretty sure you need to be HETAS to legally fit the appliance. I'm gas safe and would get a qualified guy to carry out the essentials. Balls it up and you could kill some one.

You need to have the appropriate qualifications for installation, building control will be looking certificate of competence/registration numbers as minimum requirement for back boiler / solar installation, qualified plumber is only able to do so much then you have the add ons such as gas safe, oftec, hetas etc to prove competance in specific areas

p.s. thats my experience in n.i. and from what I see on this forum BC alot more strict on the mainland

you dont need to be hetas registered, but if not you do need to pay building control to sign off the installation which will cost between £150-£200 on average Per visit. I would atleast seek the advise of a qualified person. I would not assume your friends system is correct, to the current building regulations or designed as good as it could have been. safety is the key design ingredient needed as the system needs to be able to cope with the poor control these types of appliances tend to have. Its also very improtant to get the correct boiler heat output to match your systems needs, if this is not done you will get problems.

i would personally fit a thermal store.

for some general guidence.......the system must comply with manufactures instructions, all building regulations especially Part J,part G and part L which have all recently been updated (2010 ish). The cylinder must be designed to be used with solid fuel( grade 1, 28mm coil etc...) have a temp relief valve, discharge pipework to meet part G of the building regs. You will need to have all the controls required by part L of the regs like time, temp, zoned heating. You may also require Hi and Low limit stats to avoid thermal shock to the stove. NO plastic on the primary side of the installation, including tanks, overflow, float valve etc.... No fitting bends on the flow and return pipework. Heat leak radiator at 10% of heat output.
