    Distance between Hot & Cold pipes?

    And insulate the HW pipe.

    Shredding money… radiator issues

    Probably a long run of 15mm pipe underfloor to those cool radiators... ( Or a blockage) To fix: replace 15mm underfloor pipework with 22 mm...

    Help needed - radiators on one pipe system

    1. Use 22mm pipes, TRVs, lockshields for rads connections on one pipe system (to minimise flow restrictions, same for gravity) 2. Connect radiators diagonally - flow from the top, return on the bottom (other side). 3. Keep internal baffle away from return. PS: also can use full bore ball valves...

    Ground source heat pumps

    That is very true - make sure the ground loop is sized sufficiently to meet the demand. Other usual problems with retrofit install of the heatpumps in the UK: 1. Undersized heat emiters - ideally rads should be 4X the size of the old gas/oil system - warm the house up with 35 degrees flow...

    Solar hot water

    Ideally there must be a backup boiler thermostat in the top quarter of the tank, which switches the boiler on (backup heat source), when it cools down to ~37-42 degrees or so, so you always have some warm water. Having hot water on a timer was needed with old uninsulated cylinders, modern ones...

    Is your home heated up with a heat pump?

    There is one fundamental flaw with that survey, it does NOT allow multiple choices for answers on a heating sources - like a house which already has ASHP + Solid fuel stowe + Solar thermal feeding the thermal store, and uses both UFH and radiators as heat emiters.

    Niagara valve problem?

    Check the base for any scratches/contaminants in the area where the valve's rubber washer forms a seal. If any limescale there - try cleaning with cilit bang/black domestos. Wear gloves and wipe in concentric motion. Usually you need to remove the top part of the walve assembly to be able to...

    HALL of SHAME PHOTo`s

    Hmm... That soil pipe definitively needs a few more 90 degrees bends before being concreted over in order to provide steady stream of a service requests in a couple years time, and keep the folks providing directional drilling services employed...

    Immersion heaters 3 blown in two days!

    Well done for putting the voltage logger!Also you can connect two elements in series, than you would have ~1/4 power, but double the voltage tolerance.Or go for larger element, and connect it through the silicon diode (would halve it's power).Or find twice as powerful 415V version of it, that...

    Protecting Flexible Toilet Waste from Rats/Vermin

    So first we need to find a way of blocking the rats access to yours sever system. Some sort of a metal valve /grid at interceptor should do it, but the main problem is to have it in the servicable position, because it may be quite prone to the blockage by the toilet discharge.Also one should...

    Towel rail sizing

    Re: Towel rail sizing - go for biggest. It is really hard to oversize the rad in the bathroom...Is there a suggestion in the building regs, that the bathroom should reach 25 degrees, when the other rooms are at 21?I my bathroom I had put a double panel convector 800X700mm, instead of single...

    Duel entry radiators

    Also this design "benefits" from the counter flow heat exchange between the flow and return via metal valve body, which helps with keeping the heat to the main system pipes, away from the rad :-) The person designing them probably didn't know much about the laws of thermodynamics and metals...

    Boiler coming on even though heating/water are off?

    Quite a few digital boiler controls have pump "anti-seizure" feature, which runs a system for a few minutes every 24h or 12 h. It runs even when the device is in the off position (but connected to the mains power). Some would only run the pump/fan (if integrated into the boiler), but others...

    Beeeees

    Best get a local beekeeper, and with his help: So first I would try locating where the main colony is. If it is behind the chipboard or plasterboards, than you can try using FLIR thermal imager. The living colony is kept at 37 degrees, so would be visible as a warmspot on the wall/floor. Than...
