Hi, i have posted responses but they seem to have got lost in the ether. I did a boiler rating calculation . This indicated 12kw input. I have taken room measurements, rads and calculate the radiator output to be 6372kW and using various on-line calculators the heat loss works out at 5295 kW...

Hi again, I took readings to-day over a 2 minute period and calculated the heat output to be 13.889 kW. Checked this on my i pad using an app from Ideal boilers and got the same result. Over 2 mins consumption was 43 units. Supply to boiler is 22mm throughout and tested using the suggestion...

Hi, many thanks for all your responses. I will check the boiler flow rate to-morrow but can you explain what you mean by, "Much more likely the boiler output is limited to a too low value". Thanks

Hi, thanks for your response re my greenstar junior 24i problem and suggested I gas rate the boiler. couldn't find anything in FAQ can you advise please on the best way to do this. Thanks

Hi, thanks for the reply, House is a small(ish) 3 bedroom mid- terraced house with Hall, stair and landing, lounge, kitchen diner, bathroom. Loft fully insulated, EWI insulation professionally installed, fully double glazed.

Hi, I had a Worcester Bosch Greenstar Junior 24i installed 5/6 months back but the boiler has to be set to max to get enough heat around the house just now. I checked the temperature of the flow pipe from the boiler, at the boiler, and the highest it gets is 66/67 degrees. return is 10/11...

Hi, I have just replaced the seals on my Mira shower. Unfortunately I didn't not note the position of the thermoscopic valve in that I don't know how far it was screwed into the body. Having re-assembled the cartridge the shower is not only giving a scalding temperature. I'm assuming this may...

Hi, I am considering having the above boiler installed in a bedroom cupboard. The cupboard is large enough for the boiler and the required clearances and would leave ample space for shelving for airing or storage. However in the 'online ' manual the following is stated; "If fitting the...

Hi, my father in law lives in a second floor flat. His neighbour below has been complaining about water appearing on the interior window head. Her window is below but offset from FIL's window. I have checked his window and someone has filled in the underside of the wooden cill with mastic and...

Hi, I'm planning on installing a lean to door canopy above my front door. The length would be 1650mm and 500mm deep (approx). The roof would be clad with 12 Marley ludlow roof tiles on membrane paper on top of OSB. The underside will be clad in upvc shiplap cladding. Will it be necessary for...

thanks for the prompt response. the SE has spec'd a PC lintel 215 x100 for the inside, a 150 x 150 hot dipped galvanised RSA with 3 courses of facing brick on top, weep vents every 450 on first course. DPC from top of internal lintel running over RSA and under first course. If you were...

Hi, I previously posted regarding spalled lintels in a No Fines concrete house. I engaged a structural engineer regarding replacement of these. However I would appreciate your advice as to the best way of building the replacements in. The SE has specified a replacement which is 210 in height...

Hi, and thanks for the responses and valuable advice. I have had a closer look at these lintels. The sizes are 250 x 250 ( I thought they seemed a bit thin and lightweight ) The spalling on the longest lintel is over a 2m length, at the bottom, with approx 80mm thickness of concrete...

Hi, I have a No Fines constructed house and both ground floor window lintels have spalled on the bottom edges. I reckon they could be repaired using epoxy but think it may be better to replace. The lintels are precast concrete ( with 2 fairly hefty twisted rebars) both 80 high x 180 deep and...
