so you have a red book stating building regs which you cant find saying that all new boilers must be on a sealed system???
We recommend uHeat for Underfloor Heating Systems, and The Wetroom Store for all things bathrooms and wetrooms. They provide discounts for forum members.
Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws
building regs state that if u replace boiler or cylinder it must be changed to fully pumped sealed system with cylinder stat and room stat .

Hi Marty try section 6 of the Building Reg's AD Part L2B http://www.planningportal.gov.uk/uploads/br/BR_PDF_AD_L2B_2011.pdf There is a compliance guide somewhere I will have a look & get back to you.
welcome to the forum phil ( even tho you been member since 2010 :wink_smile: )
Section 4 Part L2B & just started to read through this which should provide answers.Cheers Chris, I had read and discounted section 6, mainly because its not a first installation or an increase in capacity, however a read of section 6 would make you believe you cannot replace a boiler with a larger model without almost rebuilding the whole place to a thermally efficient standard 😀
We recommend City Plumbing Supplies, BES, and Plumbing Superstore for all plumbing supplies.
