Dear All I'm confused by so many web sites saying how to tile a floor. I have a small bathroom 3m square to tile. I have tongue and groove floor boards which are striaght and sound i.e. no creaks or dips. I am planning to use a ceramic tile 300mmx300mmx10mm Do I need to screw down a...

Just an update This has solved the problem

Dear All Thanks for your guidance. Today I moved the pump further down in the system. After moving the water tank out of the way I discovered the route cause of all my problems A one way flow valve was fitted into the return pipes on both the Central heating and Hot water circuits. This...

I want to do away with the 2xdiverter valves and fit one 3 port diverter valve to cure an air lock problem. I have proven that if the central heating circuit is left open after switch off, then the airlock problem does not occur. The three port diverter valve will be configured so that the...

Dear All I need to fit a honeywell 3 port diverter valve V4044C into my central heating system. Due to space constraints I need to fit it with the motorised valve body beneath the pipework. The Honeywell instructions say not to do this. Is this an absolute No no or are they making...

I just checked the pin and it does move in and out freely. Thanks for the tip. I shall change the TVR ASAP. Rob

Dear All I have a worcester bosh 30CDI conventional boiler fitted into an open vented system. I have a "S" plan design. I have TRV's fitted to all radiators and and honeywell automatic DU 145 bypass set to 5. I am confident that the system is clear from blockages as most of the piping is...

Dear All I have a worcester bosh 30CDI conventional boiler fitted into an open vented system. I have a "S" plan design. What setting should the automatic bypass be set to or how do work it out. Honeywell DU145 Many Thanks Bob

Dear All What temp should a Worcester Bosh 30CDI conventional be set to. I know there is personal choice here but I have no idea what the norm is. My cyliner is set to 60oC and house thermostats to 20oC The guage on the front is 1-6, then you have to twist further over a small click...

I have air vents in the systems before the pump and at the highest points. I tested the vent pipe for sucking air in using a glass of water and it was not pulling air in. Is there any point trying moving the combined feed/vent pipe onto the return side like in the diagram I saw? Would...

I have a Grundfos UPS 15-60 130. Pumping downwards. The head tank is 80cm above the pump, in the loft. The pump, pumps dowards towards two motorised valves which are 50cm below the pump. The whole system (boiler, valves, hot water tank, pump, automatc bypass, control gear) is all fitted in...

Dear All I have a worcester bosh 30CDI conventional boiler fitted into an open vented system. I have a "S" plan design which has the correct dose of Sentinel X100 in it. I have found that if I set the boiler temperature control to above setting 5, that the system is noisy when the TRV's...

Thanks for the info The pump is a Grundfos 15-60 and is already set to (1). I'll have a look at making it into a sealed system unless any other ideas come up from this post. Bob

Hi Again The "New" pump was installed in March. The air being sucked into the system has been since March as the layout of the whole system changed. Is this long enough to kill the bearing? Thanks Rob

Guys Thanks for all the help. Combining the Vent and cold feed has solved all my problems. Thanks Agile. What a super star you are! Rob

Guys Just to update you all. Changing the pipes around to a combined Vent and cold feed has stopped air being drawn into the system through the vent pipe. My system does not need any additional air vents, manual or automatic. Thanks for the guidance, Sorry for the arguments Rob

Hi all Just to update everyone. I changed my system pipes so that air is no longer drawn in through the vent pipe. The system is now fully bled and the pump is quieter. Also, speaking to three other engineers at work they all say that their Grudfos pumps are noisier, than other manufactures...

Hi Thanks for the tip. Can I ask though, the extra insulation measures 170mm high. If I only add a 75mm batten the insulation will have to be squashed to fit a loft board on top. Is this o.k.? Sorry to keep asking/ Just to go over what I want to do... I want to put 100mm insulation...

Hi I want to increase the level of loft insulation from 100mm to 270mm. My joist are only 100mm high. I don't want to loose the timber as I need some of the space for light storage. I've read on this site that I should cross batten the roof with a timber of 200 to 225 mm x 35 or 50mm...
