12p is still more than the 8.5p I pay for off-peak import, so will not change the fact that allowing the battery to fully recharge with off-peak tariff, does not matter, as will be getting more export once the sun comes out. But this may tip the balance for some tariffs. My inverter, as far as...

My Nest thermostat is only there to do DHW and CH only if we have lit a fire in the living room, in the main the Wiser thermostat controls the boiler, so not really worried any more what Nest does, however today heard the heating running, but living room warm from sun through windows, so looked...

I note at work we do have a one pipe system, steam goes in one end, and water dribbles out the other end, there is no return, but somehow I can't see that is what people call a one pipe system, does not matter if in series or parallel you need two pipes to every radiator, but I notice some...

Yes, OK, stop losses first, or at the same time, but if the heat pump does not work with poorly insulated homes, neither will it work with well insulated homes. Yes, I see we have a 60 amp fuse in the supply to many homes, so 40 amps for the house we have 20 amps for the heat pump, so 4.6 kW...

She wants to come in, we have a cat flap, and she uses it to go out, there is a delay coming in, as it has to detect her chip, there is a Ferrol cat we feel sorry for, so at moment sellotape over the catch so free for all, has been like that since first snow, but not only does she want letting...

Not official been given it yet, it will be my birthday present. So not got the instructions out of the box. So did a google, Instructions in loads of languages except English I have 4 x 2 Ah 20 volt batteries, I wonder if this grinder needs the 4 Ah version. Do I need the larger batteries?

I know heat raises, but I would have thought a flow would have been started, with water flowing up the centre and down the sides. Stratification (water) is shown for large bodies of water, but a hot water tank is quite small, also does it matter as to size (power) of the heating element, will...

There are many TRV heads, some which are truly smart, working out how long it takes to heat a room, so it can start heating the room at the right time to be to temperature when ready to be occupied, and some which only control the temperature to within 3°C of some random set point, where one has...

I did try it and DIYnot did not come up. But we see questions which seem to be just using us to search for people. The number of times I cut and pasted and added installation manual after the device being talked about to get the answers asked for. OK, sometimes it is about knowing what to ask...

What does oil cost me, I really don't know, but to make it last a little longer, so only one fill up per year, would improve things, and we have off-peak for 5 hours per day, so is oil less than 8.5p/kWh? And would the heater say a 2 kW version, last 19 hours? I have a large hysteresis in the...

I know there was a light railway act, speed limits, enclosure of moving parts, use of platforms etc, but some systems seem to encompass all. The railway engines which ran across roads had bells, as well as whistles, but if I look at the Welshpool & Llanfair light railway, the engines look the...

OK, the system works, and is reasonably cheap to run. But the hysteresis is rather high. It took some time to work out what the graphs are but found it in the end, the green bit (last graph) is outside temperature, green line actually temperature, and black line the set temperature. The first...

Oh dear, seems no solar tomorrow, but exported 2 kWh today. I don't really worry about it, but being able to predict solar production would help to if worth doing washing overnight with off-peak or in the day using solar. With my EV tariff, no argument better overnight, but with some tariffs...

I found turning the thermostat (TRV) to 20°C at 7 am, would not get the room to 20°C until around 10:30 am, but set it to 22°C at 7 am then 20°C at 8 am and the room would be at 20°C at 8 am and stay there, as the anti-hysteresis software built into the TRV head (Energenie) was simply OTT. The...

Found wet and clearly scared, put him is an empty pop corn bucket, gave it a little cheese, and allowed him/she to dry out and warm up, before taking outside and releasing. He ran off into the under growth, seemingly non the worst for the trip in our cat's month, but what should we do in the future?

There has been now for 6 months a bleeping in my flat, which at first I thought was the smoke alarm, but after hunting today my daughter found it was a Carbon Monoxide Alarm XC70 since no one lives in the flat, not really a problem, but it would be good to fix it for the odd time someone says...

What error, not seen any error in the video, if neutral is not connected it will trip, that's not deadly, what are they trying to say?

The filament LED I regarded as being for display, seen them in pubs, often need to take menu outside to read it as light so poor, and the cob LED reverse, it does not look very good, so in the main I fitted the pearl LED bulb which basic shines up from the base, and the cover defuses the light...

What a picture of Snowdon has to do with schools closing, I don't know, ask the BBC, but clearly snow is causing problems, just been out and blown it off my drive so safe for postman etc. Leaf blower does a great job. We expect post, milk, bins, etc, to be affected by the snow, but why would...

I am watching the temperature in one room (3) drop, OK the sensor is on the windowsill so the coldest place in the room, this room has no heating, used as a laundry room, so the washing machine and tumble drier do heat it a bit, and clearly above freezing, so that's not a problem, but moving to...
