    Gas valve on fire?

    Hi everyone, My customer has a gas fire (Gazco Logic HE fire, about 10 years old). It's a slide control fire. The fire has become difficult to light. One has to push a lot more firmly down on the control slide to get it to light. At which point, all is fine. The pilot is good, new battery...

    Is this an accumulator?

    The house is in a suburban street. But we can't find the outside stop tap - the water board is coming out to investigate.

    Is this an accumulator?

    Hi all, Does anyone know what this is (in a kitchen cupboard, under the kitchen sink)? I'm wondering if it is an accumulator. Mains water pressure is very low in the property. There's a bleed nipple on top, but it seems very small for an accumulator. Thanks for your advice everyone. Jennie

    unvented cylinder v combi store

    Hi Shaun (and everyone else) I've nearly got my head around the rad sizings. So... flow temp from boiler 55c gives a DT25. Rads are sold advertised at DT50. Conversion factor is 0.406. If a room has a heat loss of 1000w, 1000/0.406 = 2463w radiator. This is under Part L, which came in June...

    unvented cylinder v combi store

    Hi Shaun Thanks so much for your advice. Big radiators it is then. Just one more question - where does dt 24/25 come from? The regs say a max flow temp of 55 (55-20 is dt35). However, I'd lose another 10 percent efficiency by piping up the radiators BOE. That's as far as I've got with it...

    unvented cylinder v combi store

    Hi everyone, My customer wants a 35kw combi boiler (I recommended an unvented cylinder, but the combi won). I'm now planning the job. New pipes, new rads, new boiler, new gas pipe. It's my first entire heating system (since my apprenticeship) so I haven't sized and designed a entire system to...

    window behind shower enclosure??

    Hi all, I've got a new customer who wants a bathroom fitting. This would include a shower tray, and shower panel being situated partly across a window. It's far from ideal, but they've already bought the shower tray/panel/etc. It's a tiny bathroom, with no options for changing the layout...

    Unvented cylinder recommendations??

    Hi all, I'm due to install my first unvented cylinder. (I've had my unvented ticket for several years, but not actually done a brand new unvented install yet). It's a house renovation, with a new hw and heating system. The house currently has an old gravity floor boiler, that will be coming...

    unvented cylinder v combi store

    Such low dt. Is that due to the new regulation, of sizing radiators for the lower water temperatures that suit the renewables/heat pumps?

    unvented cylinder v combi store

    Hi all, My customer is renovating a house. Complete renovation of the plumbing. It's a three-bed house for a young family of 3. It will have one main bathroom (bath and maybe an over-bath shower), plus two shower ensuites. I have yet to check the incoming water pressures/flow rates to the...

    Electric water heater - recommendations?

    Hi all, My customer needs a new water heater/boiler - preferably electric. (Getting the gas pipe through to the desired location is a bit of a no-go. It's a tiny stone-walled, screed floored terraced cottage, with no easy route for the gas pipe. So we're looking at electric options). Two people...

    Condense pump pipe run

    Hi all, I'm due to fit a condense pump on a boiler install. I'd love an easy install. The little plastic pipe from the condense pump obviously goes up first. But after that? Can I get away with a short (3m) horizontal run before I run it into the soil stack? Or would I be pushing my luck...

    Caronnite versus Beauforte/ reinforced bath

    Hi all, My customer is choosing a reinforced bath. They're looking at Carronite and Beauforte/ reinforced baths. Any idea on how they compare? They both look like decent brands to me. Thanks everyone, Jennie
