    Drainpipe drain diameter and minimum slope

    Hi, Not sure if this is a pluming or a building question really, but guessing closer to plumbing. I will be digging up the patio area as part of the reconstruction of my house, and I will have the opportunity to lay some rainwater drains to remove the current situation of the rainwater running...

    Ideal floor insulation thickness

    OK, thanks for the replies. I don't have a much depth as I like, unless I dig down more. I could but I'm lazy :-) and I'd rather use the more expensive PIR than dig more. Any savings may end up being cancelled out by the cost of disposing of the old soil anyway. Another reason I want to use...

    Ideal floor insulation thickness

    Hi, I'm currently renovating an old house in the Czech Republic, planning to install underfloor heating. The old floors have been dug up down to the soil, and there has been a new damp proof course put in the walls, ready to be joined up to a damp proof membrane in the floor. I'm trying to...

    What Earthing system do I have?

    Thanks for your reply I have just opened the cabinet on the wall just after where the main supply comes in from the overhead cable and the Neutral is labeled PEN. There is also a diagram on the inside of the door which suggests than the PEN conductor be earthed on the consumer side...

    What Earthing system do I have?

    Thanks for your reply. I assume that, as this is how the system is installed I should not disconnect the link between neutral and earth until the earth rod is tested and verified as able to provide a satisfactory earth. My concern is, with neutral connected to earth, am I effectively...

    Earthing systems

    Could I draw the attention of all you learned people to I post I made in the Electrics outside of UK section? //www.diynot.com/forums/electrics-abroad/what-earthing-system-do-i-have.295279/ It seems that that section does not get as many views as this section, and I have had no...

    What Earthing system do I have?

    Hi, I live in the Czech Republic and I have an old consumer unit that needs updating, and on inspection, it has an unusual earthing system (possibly not unusual for the Czech Republic). Here is a basic diagram: It's a 3-phase system with a earth wire heading towards the ground ( I am...

    Thermal Store or Unvented Cylinder

    So what your saying is, you dont like them, but you believe that I have no alternative, if I want to add a wood burner and solar panels. Is it not worth investigating the possibility of added these items to an unvented system, especially as these systems are much more common in europe and you...

    Thermal Store or Unvented Cylinder

    Apologies for my ignorance, but what is the difference between a heatbank and thermal store? And why would you avoid them?

    Thermal Store or Unvented Cylinder

    Thanks for the advice, I didn't think of the possibility of having a thermal store AND and unvented cylinder, with the unvented cylinder being heated by the thermal store. I just had in my mind that it was one or the other. It would take up a fair bit of space though.. This would give...

    Thermal Store or Unvented Cylinder

    Hi, I have recently emigrated to the Czech Republic, into a house that has a relatively old boiler with sealed CH and an 100 litre unvented cylinder for the DHW. The system is great as there is plenty of hot water at a good pressure. As the system is old (1998), and my water comes from a...

    Fitting of zone valves

    Hi there, I want to fit zone valves to my central heating system to separate the upstairs and downstairs of my house, each valve controlled by a seperate timer/thermostat. In my 'boiler room' the plumbing is fairly simple, with the flow and return going upstairs teed off near the boiler...

    Combi Boiler Problems

    when you say blocked solid, i assume you mean the heat exchanger? You have to remove it from the top and give it a good clean out? I think its just held on with compression fittings?

    Combi Boiler Problems

    Hi, I have a problem with my combi boiler switching the gas on and off during hot water flow, leading to fluctuation in the hot water temp, very frustrating whilst showering! This did not used to happen. Also there is a loud squeal just before the gas turns off. At the moment the central heating...
