LA3222 Posted February 15, 2021 Author Share Posted February 15, 2021 @JamesP how do you find a 300l UVC? If you could go back and increase the capacity would you, or is 300l working out ok with four adults using DHW? Link to comment Share on other sites More sharing options...

We have never run out of hot water, probably happen now.... due to the capacity of the cylinder. The DHW is always on, not timed unlike the heating. We had a few families visit last summer and no one mentioned a lack of hot water. Presently we have another adult lodging with us. On sunny days the tank is usually back up to temp via the PV diverter by 10am during the summer. I guess the next size up is 400L. Link to comment Share on other sites More sharing options...

The Government creating artificial drives to encourage uptake of renewables tends to lead to homeowners switching over with little understanding of what they are and to what homes/circumstances they are suited to. Unscrupulous installers don't care about the aftermath! Most people on here are focused on airtightness and insulation levels. In these circumstances I fail to see how they are nothing but a good option for providing both DHW and heating. I expect they are no different in terms of peaks and troughs in power usage than any other source when considered across the full 12 month weather cycle. With Solar PV you can then get around 3:1 output from any energy generated by panels and use the ASHP throughout the day rather than trying to confine yourself to off peak energy usage? Yes the initial infrastructure can require some capital outlay which some may balk at. Myself, I tend to take the line of it costs what it costs, I see the work I do know as putting in the infrastructure and then over the lifetime of me living there it will work out very cost effective, even taking ASHP lifetimes/ PV panel lifetimes into consideration. If any of them require changing it will not cost so much as the 'infrastructure' is there, its just parts change. I am in an all electric situation, with 280m2 to heat and DHW for 2 kids who like long showers to consider. An ASHP and PV makes sense to me. My reasoning for PV is that is is likely to pay me more back than the money being sat in the bank, particularly if paired with an ASHP. Link to comment Share on other sites More sharing options...

There does not seem to be many retailers selling them, most are your RHI companies and they can poke that where the sun don't shine! I could only really find Wolesley, SWAT and some eco store. Midsummer have started selling them now - I say 'selling', I mean ripping people off? Went with Wolesely, I'm just waiting for the obligatory 'we are out of stock' email on Monday morning. If they are, it's no drama as I won't be fitting it for a couple of months. But yeah, the market isn't very competitive for these?♂️ 1 Link to comment Share on other sites More sharing options...

Nah, part of the reason I decided on getting the pre plumbed cylinder is that alot of the stuff is already on it and connected up to the FTC too. A lot less for me to think about. If I'd bought all the parts separately I don't doubt that I could do it, I just felt the cost saving that way wasn't worth all the extra hours I'd have to put in with reading pams etc to get it right. 1 Link to comment Share on other sites More sharing options...

Input power is easy, output power needs the flow and return temperatures uplift and the flow rate.

LA3222 Posted February 23, 2021 Author Share Posted February 23, 2021 As expected, an email from Wolesley to say they don't have it and can't get it. Why sell me one online then? Had another look at Midsummer Wholesale, thought their pricing was steep when i had a quick look previously but what i hadn't done was log into my 'trade' account! Logged in today and found the price is better than anywhere else I could find so i have now ordered an 8.5kW Ecodan ASHP & 300l pre plumbed cylinder at about £4900 before tax which I didn't think is too shabby. Wait time - 84 days! If anyone wants to use Ecodan ASHP I suggest you get your orders in sooner rather than later. 2 Link to comment Share on other sites More sharing options...

Ive phones my local Worslesy branch to ask about the purchase of an ASHP, the person I talked to stated that they had closed their renewables business and didn’t know if they still supplied ASHPs. He safe I an get back , he never did, Very poor Custer service. Edited March 6, 2021 by Triassic Link to comment Share on other sites More sharing options...
