  1. Nu-Heat do supply only on Nibe ASHP's.
  2. We're having trench foundations. To get to the plant room (less so of a room, but more store cupboard housing the cylinder), it needs to go across two trenches, and therefore through two sets of 100mm block underbuilding Thanks. I've dropped an email to our heating engineer who's installing the ASHP and cylinder. I feel like the only reason this wouldn't be the suitable option is a lack of space in the cupboard. **I have no idea the amount of space required at the mains entry point**
  3. Our foundations are currently going in and our groundworkers and I have been in discussion regarding routing of services beneath the slab. For the entry point for water, we have two options; beneath the kitchen sink at the edge of the property, or routing the entry point in the cupboard housing the water cylinder, which is in the centre of the property. It'll cost a little more to get the supply to the centre of the property as we'll require lintels, but it would be my preferred entry point as it would simplify the plumbing job later in the build and would reduce the amount of plumbing around the kitchen area (in comparison to a mains entry point beneath the kitchen sink). Does anyone have any feedback, positive or negative about bring mains entry to the water cylinder store cupboard?
  4. We instructed our meter installation on 22nd June 20. It was installed Monday this week! In part, that will be because of our decision to use Scottish Power. They're best avoided...
  5. I am torn. We'll be installing the Zehnder Q350, but unsure whether to purchase the pre-heater with it or not. We are based on the west coast of Scotland, right on the coast. We very rarely get snowfall or frosts (although it was frosty for a few days shortly after New Year) and winter temps very rarely drop below 1-3 deg - even overnight - as a result of the gulf stream affect. However... despite all this, it is still Scotland and who know what the weather can throw. My gut is saying no, but head is saying yes. Any thoughts?
  6. Yes, certainly does. For the time being, I see hardware advances slowing whilst advances in communications and technology such as blockchain advancing everyday use of tech. I read somewhere on BH it was needed to sell electricity back to the grid.... Yes. Would be good not having a massive bank of batteries in the corner. As we don't have gas available where we are, I'm keen to have battery storage on site so that in the event of a power cut, we can still heat the house (no wood burning stove). The longest power outage (according to neighbours as it predates us living here) is just under 2 weeks. 2 weeks during winter - it'll bound to be during winter - with no heating and particularly hot water could be an experience!
  7. Perhaps. It just feels like covering a roof to generate 30p per sunny hour doesn't offer the mature solution that the world currently requires. If a product was launched with x5-10 efficiency at a strong price point, it would revolutionise the industry over night. If there is money to be made, you can be sure someone is working on development. Nethertheless, even if the tech remains the same, the government will eventually need to support installations, which they currently don't do. In Scotland, an ASHP that would have cost me £10k in 2020 will cost me £2.5k in 2021 as a result of grants. Support for PV will come. Eventually... And plus, I need to wait for smart meter support in our area anyway. 🙄
  8. Going back to the PC analogy, I am not comparing a PC running XP (2005) to a PC running Windows 10 (2015). I am comparing the movement of the general technological shift from PC to smartphones/tablets/ultrabooks. With the amount of focus on green energy, new technology will enter the space to meet the demand of this growing sector. There has never been an industry, product or sector that has completely plateued technologically speaking, especially one that still seems relatively young in the growth cycle of that market.
  9. Ideally, I'd just cover the garage roof, which is already preexisting so the roof is already there. If we were to cover the section of roof on the house, it would be a £200 saving. Yes, can see the benefit of that. I don't dispute the price decline, just the technology and the efficiency of that technology. If it takes 10 years to pay back, I can 100% guarantee that the tech will significantly mature well within that period to the point where the current models are relics. It feels like purchasing a PC circa year 2005 and then having to use that PC until at least 2015 to get your moneys worth. In that 10 year span, tech had moved on so far that the units purchased in 2005 where obsolete. The tech still doesn't do what we all want it to do - become self-sufficient (unless you throw £££ at it - but that will come. I would rather pay £10k for a system in 5 years and gain an £8k grant from the government (which will be offered at some stage as they chase their green targets), so a net cost of £2k, to get a system that does what is needed - generate enough electricity to be self-sufficient, rather than be stuck with a system installed now that partially does the job and spend more money to do so since there is no grant or FiT (or similar). Good to know that. Cheers. The store cupboard door is a skinny one - 686mm. Which would there make it a 11mm gap.
  10. I looked in to PV and honestly, can't see the hype in current circumstances. We'd have enough space for a 4KW system spread over a southern facing roof on the house and the southern facing face of the garage roof. It would take 10 years to pay back and without a battery unit (which is unaffordable on current budgets), a portion of the electricity generated will be lost. We aren't able to fit a smart meter in our location at the moment, which I believe was a prerequisite to have electricity fed back to the network. PV and battery technology will be unrecognisable in 4-5 years compared to what we see today and will gain significant awareness as the government chase their green targets. My plan is to have this retrofitted when the technology has matured with grants and offers similar to FIT return. Ideally, we would just utilise the roof space on the garage (since this is out of sight of the property), and fit the battery units in the garage where the meter position is. In practice, our build has a lot going for a PV installation; we have uninterrupted southern facing roofing and have a three phase supply fitted to allow us to optimise overgeneration to be fed back to the network. But on tight build budgets, for technology that will inevitably improve in a few short years, can be retrofitted and currently has no 'perks', I don't see this as the time to install. In 5 years, we'll likely be in a position to own an electric car, we'll have better batteries installed and would be able to fit a 16+KW system where I currently am able to fit 4KW to allow the system to be a little more self-efficient and cost effective than it currently is.
  11. 70w is pretty decent. Around 1p an hour. She has a thing against tumble driers... Damage to clothes and unnecessary power consumption. But throw a new born in to the mix with the increased washing load, and I can see that opinion quickly changing!!
  12. Yes, the COP of the ASHP but as we had no UFH upstairs the work/grief was not worth it for the short time they are on and only in winter (IMO). Ok, so overall the cheapest way to run these rads is to use water, and taking advantage of the COP offered by the ASHP. However low wattage options are available. What are the wattage of your elements? But the better temps and simplest route for installation is electric. This cuts out the need to take any heating solutions from the ASHP upstairs saving on the plumbers time needed for the job.
  13. Are you able to achieve higher rad temps compared to water coming from an ASHP? It certainly does seem to be the easier option here. Any advantages of running water to these rads?
  14. Yes, I'd seen others mentioning it to be fine with an MVHR extract point. With this constantly extracting - even when washing is not in that room - it should remove any moisture particles to keep it damp-free. The room isn't that large. It is 2.06 * 0.88m on the top floor of a 1.5 story. So 0.92m of the 2.06m length of the room is full height. It is probably just about large enough for clothes drying and nothing much else. Not sure. It was going to be water, but seeing as though we're not installing rads to bedrooms, it seems logical to consider both. Advantages of water - cheaper to run? Advantages of electric - negates having to plumb any heating upstairs so cheaper to install.
