Someone will know but I think it's a calculation about the following: Volume of air exchanged times the weight difference between the humidity level of the warm moist air before going into the MVHR and the lower temprature air's dew point coming out of the MVHR after losing any heat. So: Temprature and humidity level of the air beforegoing into MVHR will give you the weight of the air at start. Temprature and dewpoint of the air leaving the MVHR will give you the weight of the air at end. Start weight minus end weight will give you condensation weight. Times this by volume of air passing through MVHR per hour and you have the amount of condensation produced per hour. Then someone boils a kettle or has a bath or shower and all your calculations go to pot! Sometimes ours is nothing sometimes a trickle. I don't think it's poisonous. Can't you get it out to a soak away? I await the flood of corrections to my thinking... Marvin

Oh! Better get it out the skip. It's gone like a car windscreen.

Welcome. Always good to ask ahead of time. Marvin

One of the PV panels I bought was badly damaged and the supplier replaced it. What am I supposed to do in order to dispose of the broken one? Any ideas?

Well my guess is that if they were cheap everyone would have them. I think they would not work on a pitched roof. I'll let the more knowledgeable plough in with all the technical reasons. Good luck. Marvin

Your having a laugh!!!

The problem with Leylandii is that if you cut it back too hard it will stay bare.

Yew takes along time to grow...

You just can't leave it can you.... ???

Manufacturer technical department states the existing condensate drain will remove condensation produced when either the inlet air is colder than the exhaust air, or when the exhaust air is colder than the inlet air. so all good from that point of view.

I don't know. I will contact the manufacturer and see if I can add a drain on the other side....

Good question. Yes we have a summer bypass.

Good question. ALL 4 lines of ducting insulated everywhere within the building/ loft.

Only just got the ASHP running. Purchased and will be adding one of these coils: Duct water heater.pdf Had to add an air filter as the water coil will be positioned just before the entrance to the MVHR box on the inlet pipe. This should allow condensation to flow out of MVHR box through the drain point. Yes pipework to MVHR. Yes warm and cool as set on ASHP. Advised to have separate port valves to both radiators and coil. If the coil works ok, then when cooling, I can turn the temperature down lower than I would for radiators, and just run the coil and this would avoid the risk of condensation on the radiators because I should be able to leave them off. (enough cooling from coil hopefully) That's the cunning plan! We shall see.

This model is the single phase Invertech air to water ASHP. I don't know about the other models. We're running it using radiators and a coil in the MVHR system Yes programmable cooling.

Yes but you try living without a fridge/freezer these days..

Yes. To protect the DPM from sharp edges and fill voids to make a flat surface to lay the DPM ON.

A much better way of dealing with the situation! And I agree with nod. I just wonder why specify 400mm.

At present material availability is irratic.

Ditto. Realised the same.

Runs very quietly. Almost no noise from the unit outside. Fridge/freezer makes more noise inside.
