    Wood stove boiler + gas combi

    I looked into this at one point using a Dunsley Neutraliser, but didn't proceed at the time for several reasons. Linking a solid fuel stove to a system with a gas boiler is fairly complex to understand (it was for me anyway :) ) but I thought this video I found whilst investigating the various...

    Honeywell Motorized Valve Buzzing

    I'm going to say yes, because both power heads both show the same part number as you can see below. The 'bump' on the top of the lid indicates that the powerhead is replaceable. The original ones weren't. However, according to the diagram on the old powerhead it has a SPDT switch with a...

    Honeywell Motorized Valve Buzzing

    It has a synchronous motor inside and when they get old and worn they do buzz. The motor can be replaced. See here. But if the motor is worn so will be the rest of it, so usually it's best to change the whole powerhead. See here. Neither replacements will require draining down. Other...

    Drayton Mid Position Actuator Issue

    When you say "when the HW goes off" are you saying: a) Switched off by the hot water cylinder thermostat because the water inside the cylinder is now hot? or b) Because the programmer has switched off the hot water?

    Can rad valve internal be replaced?

    Have you tried tightening the nut slightly where the water is dripping from? That usually sorts it. If not I would remove the nut and pack it pack it with PTFE.

    Recommendation for Extractor Fan

    The shower is a bit to the right of the airflow, but generally the overall layout isn't that bad, (I've seen worse) provided that there is a sufficient gap below the door to allow air to enter at the same rate that the fan is pulling it out of the bathroom. I guess your task now is to determine...

    Recommendation for Extractor Fan

    The minimum recommended air flow rate for a bath / shower room is 15 litres / second (Building Regulations Part F) but sometimes more extraction is beneficial especially if the fan doesn't continue to run on for a while after the shower has finished being used. It might be worth investigating...

    Change Hive Controller to Sunvic TLX9201

    What version of Hive are you referring to? For a combi it would normally be the 'single channel version'. And what wires are presently connected to which Hive terminals. A photo of the wires at the Hive would be good, as there is more than one way of wiring a Hive to a boiler.

    Replacing Potterton EP2002 and BG RS2 with Hive Active Heating and Hot Water thermostat

    Hey, nice job with the insulation. (y) That's because Hive doesn't provide that function. Below is the thermostat for your hot water cylinder. Whilst Hive doesn't provide temperature control of the stored hot water, this does. However, Hive will let you set the times that you want the hot...

    Honeywell Thermostat

    Interesting. I wondered if it was the old stat too :unsure: but the OP does say: So maybe it is the old thermostat, and the OP's not replaced like for like. @Kam1973 can you clarify please as terminal numbering isn't the same for all thermostats. I can't imagine though that you would ask for...

    Honeywell Thermostat

    Yes it could, because terminal 4 becomes live when heat is not required. This is the position it's shown in on the diagram. Hence my comment: Here's a diagram showing the T630B with an optional COOLING LOAD connected to terminal 4

    Honeywell Thermostat

    The wiring as shown in your photo looks right to me. Assuming that it is a T6360B. The model number and diagram will be inside the lid. For it to work in reverse I would expect terminals 1 & 4 to be connected, and not 1 & 3. From the T6360B diagram below: 1=Live 2=Neutral 3=Switched Live In...

    Is Fitting Tado Going to be Straight Forward in this House?

    There are quite a few variants of Tado. Some have hot water control included. They are used when there is a stored hot water cylinder heated from the boiler. Other versions of Tado don't have hot water control generally used with combi boilers. Examples of Tado with hot water control are...

    Replacing Potterton EP2002 and BG RS2 with Hive Active Heating and Hot Water thermostat

    It's obvious really but I forgot to mention that the boiler's thermostat needs to be set 5 to 10 degrees higher than the hot water cylinder thermostat. Otherwise the cylinder will never get hot enough to switch the cylinder thermostat off.

    Name of this plug/connection?

    Ah OK. When you said you were looking for 'name of the plug connection' in your title and then showed a picture of a socket I thought you wanted the plug to go in it...... .....not the power supply itself... :giggle: :giggle: :giggle::giggle:

    Name of this plug/connection?

    Looks like the same 2-pin 12v connector that is used with 12V garden lights maybe? There's an example here. I've had several different brands of garden lights over the years and they do fit each other. Whether the kitchen lights are the same I don't know but for less than £5 might be worth a try.

    It will work either way around, it's just an on / off switch. But convention is usually that the right terminal (black wire) goes to 1 and the left terminal (grey wire) goes to 3

    Hive instal. Logic ideal wiring

    Sorry can't see any picture. Also, which version of Hive do you have? Single channel for a combi boiler, or dual channel for heat only boiler. Ideal Logic comes in both variants.

    Hive instal. Logic ideal wiring

    The wiring at the Hive end could be right provided the boiler is wired for 230V control (most do use this method) some use 24v for their control circuits in which case making the link between L and 1 would put 230V on a circuit designed for 24v and damage it. You don't really say where the wire...
