    Is a 'load compensating' thermostat worth while?

    I'm in the final stages of changing over from an open vent system (ancient Ideal Mexico Slimline boiler) to a modern sealed system using a Worcester Greenstar 36CDi Compact combi. I was originally intending on reusing the Honeywell CM927 programmable thermostat (the only modern bit of my old...

    Choosing the correct size of combi

    Now that nearly all boilers can modulate their output over a wide range, is there any good reason not to go for a larger output model (within reason) in order to get better a better hot water flow rate? I am planning on replacing my old Ideal Mexico Slimline heat only boiler with a combi in the...

    Cutting flue hole in rendered wall - drill from inside?

    I'm looking to get a new boiler fitted in a different location to the current boiler, so will need to drill a hole for the flue. A gas safe registered mate will be doing the install but I'll be doing some of the prep including drilling the flue hole. The property is a 2nd floor flat with...

    Will this pass an EICR?

    I may need to relocate for a while and am considering renting out my flat and have just begun researching my obligations as a potential landlord and it seems that you now need to have interlinked main powered smoke alarms and an EICR for the property and PAT test appliances etc (property is in...

    What do you call these / where can I buy them?

    I'm in the process of replacing an ancient leaking Sunvic Duoval 3 port valve. Rather than replace with the same thing I decided to replace with a standard spring return Honeywell valve and get rid of the large duoval relay box. Since the old valve had what appeared to be 3/4" connections, I...

    Old Ideal Mexico - keep or replace?

    I've just bought a new flat but it has a rather ancient boiler - its an Ideal Mexico Slimline which I reckon dates from when the property was built in 1986/87. Any views on this boiler? Are they generally reliable (looks very basic, so probably not too much to go wrong) and can you still get...

    Fan assisted storage heaters - any use?

    Does any one have any experience of modern fan assisted storage heaters? I am usually out all day, so would they still retain a decent amount of heat at 7pm? I am considering buying a flat in a building with no gas, so was wondering if fan assisted storage heaters would be OK or if I might...

    Electric heating questions

    I'm looking at buying a flat that currently uses old electric storage heaters for space heating (building has no gas), and was wondering how do modern electric heating systems compare with GCH for running costs - past experience of storage heaters hasn't been good. Are modern storage heaters...

    Reducing cold water pressure for mixer tap shower

    Since my previous thread on mixer tap showers got a bit off topic, I thought it best to start a new one... If I were to install a mixer tap shower (e.g. Mira Extra) to my bath which has mains cold water and gravity fed hot water, I gather it is unlikely to work well unless the hot & cold...

    Mixer tap showers - advice required

    I would like to fit a shower over my bath, the easiest way would be to replace the bath taps with a mixer tap that has a shower attachment but I'm not sure if that would work with my plumbing. The hot water to the bath is from a HW tank fed from a cold water tank in the loft whereas the cold...

    Problems with new style Potterton Suprima PCB

    After experiencing the usual lockout problems, I replaced the PCB on my Suprima 40 with one of the style ones (part no. 5111506). The boiler has been fine for the last three years but is now playing up again. Sometimes I get the flashing green light (temp satisfied) almost immediately after...

    ACL/Drayton mid position valve query

    I need to replace the actuator on an old ACL Lifestyle mid position valve (model 679H340-3OLO) but it seems that this valve has been replaced with a newer Drayton model with a removable actuator. Does anyone know whether or not the newer actuators will fit the older valves, or would I have to...

    How can I identify my supply type?

    I'm trying to identify what type of electricity suppy I have, its either TN-S or TN-C-S but I can't tell for sure because the earth connection to the incoming supply is hidden under a plastic cover. Can anyone tell from these photos, or do I have to lift the plastic cover (green arrow on 2nd...

    Hello all, My 2 year old Suprima 40 boiler isn't heating properly :( , it seems to only heat water to about 60 C even when the thermostat is turned to maximum. The boiler is feeding a vented system comprising 11 radiators plus hot water tank. Thanks to this board I'm aware that this...
