alternative to Homely - HavenWise. Anyone used it?

Tim441 · 2024-10-08T14:39:51Z

Interesting article in the Telegraph.. includes: HavenWise for heat pumps. Has anyone heard of it.. or used it? Extract: The established brands include Homely and PassivUK, whose optimisers have been independently shown to save 20 to 30pc. The latest entrant is a start-up called HavenWise, the brainchild of Alex Nelson, a former captain in the Royal Logistic Corps with a masters degree in robotics, and backed by Carbon13, a climate technology investor. Last spring, HavenWise demonstrated its system on my heat pump during two days of near-identical weather and the result was astonishing. The combination of its optimiser and the Agile tariff worked out 60pc cheaper than a standard tariff with no optimisation. The company says it achieved similar results in longer tests with other heat pumps. On that basis, had I been using Agile and HavenWise over the previous year, my heat pump bill would have fallen from £1,194 to £478, a saving of £717. My total electricity bill (I don’t have gas) would not have come out at £2,096 – roughly in line with the average Ofgem tariff and Energy Price Guarantee over the previous year – but a third lower at £1,379. For this year, if the weather and Agile tariffs stay the same – which they won’t – and with the Ofgem cap at £1,717, I’m guessing it would be around £1,200. But these savings are at the upper end of what HavenWise would expect, cautioned Mr Nelson, because I had not previously been running the heat pump in its most efficient weather-compensation mode. As the company tests its algorithm on many more heat pumps this winter, it expects the savings to be lower. “It’s difficult to forecast precisely”, said Mr Nelson, “but we think the average savings will settle at around 50pc.” If optimisers can deliver savings of more than 30pc, it could give heat pumps a decisive advantage over gas boilers, according to Nesta, a clean energy think tank. Its modelling shows that with the current installation subsidy of £7,500, heat pumps would then undercut boilers on the total cost of ownership – including purchase, installation, maintenance and 15 years of energy bills. “If the optimiser can save 30pc, heat pumps would cost less than a boiler every month, all in”, said Andrew Sissons, deputy director of Nesta. “That makes it easier for banks to offer financing to eliminate the upfront cost for the consumer, so this could be a pivotal moment.” Those kinds of deals are already beginning to emerge. Swedish company Aira is installing heat pumps in the UK at no upfront cost. The Heat Geek installer network has launched a similar offer which includes an efficiency guarantee. Homely and PassivUK’s optimisers work through small electronic devices costing around £200 that need to be wired into the heat pump by an approved installer. HavenWise operates through the cloud and needs no extra equipment – provided the heat pump is Wi-Fi enabled – and will charge an annual subscription of £50.

I am intending to try Havenwise when Samsung eventually provide the wifi kit which was supposed to be included with the pump, but they seem to be reluctant to do so. Mine is Gen 7, 12Kwh. At the moment I am using Planet Atmo device which is great for data, but has no controls.

@alfapat For Havenwise, your heat pump needs to be internet connected like @broadsman mentioned. Most heat pumps that are currently being installed are internet connected. And if they are not, recent installs can easily be connected with a WiFi kit from the manufacturer.
I understand you have a heat pump that was installed 8 years ago. Is yours internet connected?

@hcas this is probably a dumb question but, how does one know if it's internet connected?

Samsung are reluctant to do so? Please elaborate.

@editor When the Samsung was delivered I was not aware that it should have included the wi- fi kit DB98-40278A, as my installer had already suggested that he install the modbus board and a Planet Atmos device to enable him to keep track of, and diagnose, any problems which might arise.

However, because Planet do not yet offer any control of settings, I subsequently looked at (Homely and) Havenwise and found that a wifi connection was necessary, but that the kit should have been included with the pump. However, it had not been supplied and my supplier is having difficulty getting Samsung to accept this, and indeed do not seem keen to sell us another one either. Enquiries are still ongoing. If anyone from Samsung is reading this, can you help me please?

Quite honestly, Samsung are a nightmare. Most manufacturers have off days, but Samsung seem to default to being consistently useless and incompetent. Their approach to resolving issues is appalling. I’ve personally forwarded countless problems with Samsung heat pumps from these forums to their head of heat pumps; while they acknowledge the issues, nothing ever gets done. Their customer support is abysmal, which is why it’s no surprise they’re being awkward. I'll contact them on your behalf. What heat pump model and size do you have, and I'll confirm if the wifi kit (DB98-40278A) should have come with it.

I would re iterate that thought.

The cowboys who fitted mine 8 yrs ago added the problems to my unit with the installation .

When they went into liquidation 6 months after endless faults and never getting fixed , nobody would take the resposibility on apart from one firm which was appointed by Freedom pumps to take on Samsung .The firm altered or corrected the plumbing but couldnt fix the wiring set up.The pump has worked fine itself but no one up here in Moray wants to know.

@alfapat Sounds to me as though we require an Ombudsman solely to deal with heating installations.😒 Toodles.

@editor. Thank you for the offer of contacting Samsung on my behalf. My pump is a Gen 7; 12Kwh, model AE120CXYBEK, and the wifi kit details were supplied in a phone call which I made to Samsung Aircon around October last year. I am happy to supply my installers details and their umbrella supplier, but I think that these should be in a direct email or PM if you need them.

I hope your contact will be able to move this forward to my satisfaction. The pump is working well and I am pleased with it.

Thanks again

👍
