Home energy efficiency

Ok, serious question here (like I'm going to get any serious answers, but hey-ho). Apart from the obvious like double-glazing and loft insulation, how do I improve the energy efficiency of my home?

Them twats EDF asked for meter readings, which I've now provided and they've upped our dual fuel direct debit from £158 to £201!

I suspect you have solid walls……but if cavity then having insulation pumped in will make a massive difference…if done properly. Don’t know if you can get a grant for this?

The place we are in now and our last place both had the old ‘standard’ 4” of loft insulation….I added extra, most of it about a foot deep and that made a huge difference.

Other than that a ‘smart/learning’ control system will pay for itself pretty quickly.

Um, what's a smart/learning control system?

I'm starting to think there's something wrong with our gas meter. There's no way we're consuming as much gas as what the meter is indicating.

Adding more loft insulation is a good idea.

Pow-Lo if the insulation options are limited try turning the heating down by 1c - it makes a big difference as energy use increases exponentialy the higher the temperature increase rewuired….and nobody will notice,,especially if you don’t tell them….. Also if you have a hot water cylinder review how often that gets heated - ours is only on for half an hour each day at 7am and 4pm, plenty enough Most days. Oh, and if your cylinder isn‘t insulated get a jacket on it…two in fact, one is never big enough.

control system that ‘learns’ your usage pattern, how the house behaves in terms of heat retention (or not!) and adjusts itself accordingly, as well as reading outside temperature movements and receiving weather forecasts via interwebs and factoring those in. They really do work - no point in heating the house when the forecast is outside temperatures will increase and do the job for you! Many also monitor House occupation via mobile phone movement and adjust themselves automatically when you leave the house and when you are on the way home.

Ours is a few years old now and doesn’t do all that stuff but has features such as ‘I’m away between’ which drops everything down to frost protection only when we are away and switches itself back on so everything is back to normal at the pre programmed return time.

Anotyer energy saver is having the boiler regularly serviced, particularly if it is old.

You can ask your provider to organise an independent check if you think it's over reading.

Ours is set to 18 degrees from 0800 to 1200 and 1600 to 2100. When I come in from walking my pup in the evening, I generally knock it down to 17; for some reason, the house seems to be warmer in the evenings.

No hot water cylinder, we have a combo-boiler.

We have a Hive and I tend to turn our heating down from the app if we're both out. Not heard of a smart system that tracks us via phone signal though.

Yep, we have ours serviced annually.

Oh, and our walls are solid so we can't have cavity wall insulation.

It might be more efficient to have the heating on all day rather than the four hour gap. Definetely worth experimenting.

our heating is not set to come on at all in the morning, today I knocked it on manually to 17c when we were ready to settle down around lunchtime for the day. Below is what that looks like in terms of energy usage I.e. boiler worked flat out to get the house to 17c and then barely ticking over to maintain it.. …hence my comment re possibly more efficient to leave the heating on all,day (if you must!). That is with a five year old Valliant boiler, the ‘BMW’ of boilers :tongue: , that is incredibly efficient running alongside the smart control system.

the green bar is how hard the boiler is working, the solid line the required inside temperature and the dotted wiggly line is actual indoor temperature

How about solar pv panels and a battery? Economy 7 meter if you use electric off-peak or if you want to charge a car at night.

First question ... what sort of solid wall? brick or old stone?

Second question how old is the double glazing?

You could do external insulation or line walls internally if you really want to improve energy saving.

It‘s all brick, 1903 built.

Nine years.

Prohibitively expensive. The sheer size of the place for one thing and the outside is rendered.

Heating is gas and no EV. As for solar panels, and I’m only guessing here, but I don’t think the orientation of the house is any good for siting of them, we’re more or less north/south.

I’ve changed the Hive for the heating to be on 17 degrees from 0800 to 2130, see if that makes a difference.

Ours is Bosch, which is the Mercedes of boilers.

Might seem like a silly question but are you on a fixed tariff? as the price of gas and electricity have risen tremendously the last few months which could be why they have increased your direct debit

I was going down the solid wall insulation route as I have done a fair bit, not a clue about the cost though as I was just the monkey drilling a million holes, its very effective though

At 9 years old I would hope they are A rated windows unless the PO was a real cheapskate but its worth checking that they are properly sealed both to the brick and in regards to the rubbers in the opening parts

Spray insulation to the underside of the roof tiles/slates is effective, quick and cheap but extra insulation up there in whatever form will help

Not at all. We’re on a fixed tariff until September 2024, an apparent special rate for previous customers of GNE (who went bust early last year). Back in October we were £187 in debit and now we’re £261 in debit. I guess they want to recover their money now and wait til we’re in credit in the summer before they review it again.
