Insulated Internal Doors
We are arranging to move to an air source heat pump. The house is generally well insulated but has an unheated conservatory which we don't use when it's cold. One of the conditions is that we replace the current doors from the house to the conservatory, which are wood/single-glazed glass pane french doors, swapping for an…

Smart dishwasher with Solar
I'm not able to find the answer online so thought ask here. I have a solar array and my dishwasher has broke. I'm wondering if any smart dishwashers have the function to only run the heating cycle when the panels are generating the most, but switch off when other loads come on like toasters washing machines ect..

My year with a battery - A year of savings.
Hi All, the numbers are in… I have an old FIT system from 2014 and am currently in my 9th
year. It paid for itself in FIT payments
alone a couple of years ago, so decided to fit an AC coupled Battery and
inverter. This was fitted in April last year, 6.5kWh battery, so not huge but a
good useable amount. I got a much better…

Insulating roof space
We have an early 70s brick built house with concrete tiled roof. There is black roofing felt beneath the tiles. There is about 100mm fibreglass insulation between the ceiling joists but most of the area has been boarded out. We're wondering what is the best way to increase the insulation - do we aim to put some kind of…

What to do with a slightly spicy pillow?
If anyone uses reddit, and goes on r/spicypillows you'll see batteries that have swelled up My power bank is only ever so slightly spicy. I've basically discharged it and left it be. I could take it on a tip run with other stuff but equally not sure whether there are other alternatives in terms of where to dispose of it? I…

Rain water harvesting for garden irrigation tank size?
I've just seen they have put the unit price of water up to nearly £4 a m3, we live on a small holding and 95% of our water is used outside for animal and plants. I've spoken to Anglia water about an alternative tariff but they are aimed at agriculture/ industry, we simply don't use enough. We already have grey water…

Solar Panels on outbuilding
I have been planning to put solar panels in/on to a new roof but my Local Authority are "Planning" to thwart me. I'm already 2 years into the maelstrom that is planning an extension onto a 1924 house in the green belt. I was hoping to get rid of a 1970's pitched roof on a hideous brick extension, but so far the LA (and the…

Lowest night time rates to charge a battery, if you do not have an EV ?
What is the best electricity tariff for the lowest night time rates to charge a battery if you do not have an EV ? Trying to estimate the best sized battery to give a sensible ROI. Octopus Go or Intelligent would be great at 7.5p night rate but do not have an EV. So trying to see what is next best. Planning 4kW PV with…

Replacing faulty and old solar panels with higher wattage. FIT question.
Current situation is 12x200w panels on roof of 3 storey house. Panels are 12 years old and one has failed, as they are connected in series no power generated! Scaffolding is in place to repair and has cost £800 so wonder whether l should consider replacing all of them whilst it is up. Cannot get 200w so it is likely the…

Wood burning stoves
These are quite pricey to install but can be pretty cheap to run Do they still have the indoor air quality issues that they've been plagued with in the past? If so, that's a bit of a deal breaker

Two separate battery and inverters on the same house
This might be a daft question. Can you have two separate battery and inverter setups in the same house. I mean separate as in two different brands with totally different charge/discharge rates? I find information that seems to suggest that this is possible with solar inverter and a battery inverter and I am curious whether…

Octopus Flux - Net exporters only?
On other parts of the internet, I've seen quite a few people say Octopus Flux is best for "net exporters" Agile is best if you've got a heat pump because you probably aren't a net exporter. Even then, people often have at least 20 kWh worth of batteries. Then use solar diverters to hear water Go/Intelligent Octopus is best…

Are Solaredge Optimisers Always Worthwhile?
We are planning on putting panels on a sloping roof, orientation 190 DegT (just W of South). There are no obstacles to cause shading. One installer gave a detailed pitch on how the Solaredge optimisers work, but his concrete examples with figures were all where shading occurs at certain times of day, for example from a…

Using Growatt hybrid inverter with third party batteries
Is it possible to add non-Growatt batteries to a hybrid Growatt inverter (SPH3600), which already has one 65.kWh Growatt battery connected? For example, it seems that I can buy an array of Nissan Leaf batteries for a few hundred pounds. That's only a small fraction of what a Growatt unit would cost. Can I connect these to…

Insulating my walls
I have a property built in 1996 which uses white wool fiber in the cavity, I feel like a lot of this has dropped in the walls where its got damp from water tracking across the cavity in places, the house really struggled to maintain heat in the winter and it takes a lot to heat to a comfortable temperature. As I don't…

Solar hybrid inverter - 3.6kWh or 5kWh?
I have recently started looking into getting quotes for a solar + battery installation and been recommended 10x425W panels giving 4.25kWp (south facing). The installer recommended a 3.6kWh hybrid inverter and a 9.5kWh battery. Costwise I've been told there won't be a big difference if opting for a 5kWh inverter, and I've…
