Deema, Just a general safety comment. You should perhaps mount the cable JB that's on the floor on the wall just in case you have a leak!

jwDave, When you eventually recover the workbench to its working moisture level it might be an idea to apply a coating of oil (if not already coated) in the areas most affected. This will slow down the moisture takeup but it won't stop it. You could also add a small heater (perhaps 15 or 25...

jwDave, Relative Humidity (RH) is a factor of temperature and atmospheric pressure. As an approximation (and from memory), ignoring pressure which has a very minor influence, you reduce the RH by 10% by increasing the temperature by 2.2 Deg. Cel. Therefore you only need to maintain the...

I am also interested if no one takes it before me. Please let me know.

Deema, Spectric, et al, all raise interesting points regarding why you see your fuel consumption is lower when you keep your heating on most of the time and all give valid reasons as to why and why not this it is the case. It is a very complex scenario with multiple factors coming into play One...

Deema, Have you considered a micro CHP unit and a fuel cell? These use gas (you will need to check for LPG) to generate a small amount of electricity while providing heat, which if you are using it all the time may be cost-effective. Like solar, you can also sell it back to the grid...

Deema, The regs. (section 5.10) actually seems refers to the replacement of the complete system and not just the boiler and therefore they are trying to make the owner go down the low Temp route.

The explosion risk for small workshop extraction systems is generally very small - otherwise, you would hear about incidents occurring. Although you may have an explosive atmosphere you typically do not have ignition sources sufficient to initiate the event under normal working conditions. The...

Deadeye, You don't say how high the damp goes up the walls, or how it is appearing, so assuming it is only a couple of feet or so it sounds like penetration from the local ground level. Is the damp affecting the joists? It is likely the paint that was probably applied to resolve the problem in...

What a great workshop you have built. I know it's hard work doing it yourself but it is really satisfying - I am coming to the end (externally) of my build by installing the UPVC windows and doors and can't wait to start to use it. I will post some up to date photos later on my thread later.

Absolutely correct. You must have a balanced system as far as possible. However, with TRV's this is not always 100% possible because the flow in the system changes - the new learning pumps are good because they compensate for this and reduce electricity consumption at the same time. Don't reduce...

You will see the best saving when heating your hot water cylinder when the boiler (assuming condensing) is operating at its maximum efficiency e.g. when the return flow is relatively cold. Therefore it is always advisable to try and have the HW heating when on just after the CH comes on. If you...

If the remaining stumps in the ground are 3" in diameter or more you may be better off contracting a stump grinding company to come and remove them for you, or, you could hire a grinder and do it yourself. These will break up the soil as well for you.

Martin, Sorry to hear about your problem. If there has been any risk of effluent in the leaked water from the macerator then you must remove as much of the plasterboard as you can. From a strength point of view, the plasterboard may be compromised but more important from a health point of view...

I used scaffold boards for the formwork as they can be useful afterward.

DomP, As it really needs to be a continuous pour, not a DIY mix and lay, you probably need to contact your local concrete delivery companies and get some quotes for RC30 with and without Fibre mix and then compare with using A142 mesh. There probably won't be a lot of cost difference, but laying...

The DPM was wrapped over the former (scaffold boards) and then cut - ensure as the DPM runs up the inside of the scaffold board you create a fold into the concrete as this creates a good seal so damp can not get in between. I didn't extend the DPM up the brickwork but I used DPM between the top...

Dom P, Take a look at my workshop build thread "......Grade 2 listed building". The overall size is similar and we had a tree issue. We used a concrete pad, 200mm thick**, RC30 concrete poly fiber reinforced as this eliminates using A142 mesh and also reduces the risk of cracking. We have...

As MikeJnn highlighted it is very unlikely to be rising damp. If the leak had been there for a while, which is likely as it takes time to penetrate the brickwork/ground below, it will take months (6 - 12 months) to dry out - using dehumidifiers on site for three weeks will not be enough. I would...

Over the years I have undertaken a fair bit of work on historic buildings including repointing and rendering in lime. The first thing to note is that there are two main types of lime that are now used in historic buildings; the first is pure slacked lime, lime, or lime putty, and then the...
