Drayton 25474 LP241 (Mk4) 2 Channel Programmer

This programmer is very easy to install and use. It was bought to replace a failing existing Horstmann programmer for my elderly Mum, and it was very easy to install thanks to the universal backplate. Even though I used the new included backplate the whole installation including programming took about 30 minutes.The clock was already preset at the factory, but it can simply be 'tweaked' if it's a minute or two out.The unit has daylight saving facility for when the clocks change over in Autumn & Spring.The clock is permanently backlit, which makes it easy to read. When 'ON' a green LED illuminates to indicate whether Hot water or Central Heating are activated.I particularly like the fact that all the programming buttons are hidden under a flap, so all my Mum has to concern herself with are the two buttons on the front which advance or boost the hot water or heating as required.We have a different version of this unit installed in our home too, and both run flawlessly. Maybe this is why British Gas choose to install these as standard?Excellent choice that I would recommend.

Our old Drayton LP241 central heating / hot water heater programmer would not ‘click’ on even though the light would turn on the heating would not. We had been using a wooden spoon to hit our old Drayton LP241 because that was the only way it would ‘click’ on. But the hitting got harder and harder to the point where we gave up and got a new box. We watched some YouTube videos of how easy is is to replace old programmers and installing new ones. The old box unscrews and slides off the wall socket, which is already screwed into the wall and is wired up to the electricity, it can be replaced with a new socket provided with the new programmer, the new programmer slides onto the wall socket and is screwed down easy.

Works well, as it should

This was a straight swap for my previous Drayton controller so if that also applies to you then this is defo a DIY job for even those with very basic skills.Turn of your power at the main switchboard, undo the two screws underneath the existing controller and remove it upwards. Slide the new controller onto the existing bracket, fasten the screws to the new controller and turn the power back on.Its that simple, if your nervous pay someone £60 to install it for you!

This was bought to replace an older Drayton Lifestyle LP241 that does not have a boost function (to add an extra hour).The replacement was easy by loosening two screws under the unit and hinging it up to remove and then hooking the replacement on the two hooks at the top before hinging it down into place and tightening the two screws again. Just turn off while doing this. I'm not sure how but it remembered the settings from the old unit.My wife is very pleased to have her +1 hour function both for heating and hot water. Simply press and hold the boost button - once for +1 hour, twice for +2 and three times for +3 hours. Press a fourth time to cancel the boost.

Neat looking, easy to use and program, simple to wire and install excellent product.

easy fit worked out of the box cheaper than screwfix

My programmer, a British Gas UP1 installed in around 2002, was beginning to behave a bit erratically and also, after so many years, was discoloured and some of the marking were very worn. I was able to remove it from the wall (two screws and push up and out; you have to be a bit bold with this - mine was stiff to remove as old wallpaper paste has "glued" the programmer to the wall. Gently easing a small screwdriver along the edge broke the bond). Then remove three screws and unclip the back and I could see a CR2032 battery - which had done very well to last twenty years. Although it looked as though is ought to be replaceable it wasn't keen to be removed and rather than risk damaging the controller at a time of year when temperatures were dropping to sub-zero I decided a replacement was in order. The replacement arrived within a couple of days. I took the old controller back off the wall, did a quick check through the instructions to confirm the wiring to the pins on the back plate fixed to the wall was the same on the old and new controllers (there is an extensive table in the instructions comparing different programmers from Drayton and other manufacturers) and fixed the new controller to the backplate.It then took me a couple of minutes to programme in my times for heating and hot water (although you can leave them to the factory defaults) and everything was done. It really couldn't have been simpler and well within the capabilities of the most basic d-i-y person - just take the time to read and understand the instructions.Apart from a shiny new case the new programmer has a permanent back light, making adjustment to times easier. The only "negative" is the old controller had options for M-F, Saturday and Sunday so you could have different times for the heating and hot water during the week and at the weekend but this just added to the complexity of programming and for me having the same pattern seven days a week works fine.If you are having intermittent or erratic problems with heating and hot water replacing the programmer (particularly if it's few years old) may fix the problem at a very reasonable price before you have to call in a heating and plumbing engineer.
