New build, the developer installed two Mitsubishi Ecodan PUZ-WM85VAA monobloc units on opposing side elevations. About ~550mm between the edges of the units. SCOP sitting at 1.3 against a manufacturer spec of 3.48. Full details in comments.
Purchased a 1T Mr Cool split system. I got the main disconnect run, wired into the unit, use the thermostat for demand and nothing.
I have 120 as the disconnect but 0 at the unit. Are there hidden fuses or what am I missing.
so follow me here. a dehu is just a heat pump with the outdoor and indoor unit in one package, indoors.
a pos dehu could be $500 and they are usually junk and last a couple of years at most.
let's say you wanted to dehumidify a basement- why couldn't we just install a mini split, both indoor and outdoor units, in the basement?
a 9k btu mini split could be had for $400.
it would use about the same power as a small dehu (600 watts)
I believe it would be quieter
and it would pull more humidity out of the air.
why aren't we doing this?
I just finished installing a heat pump in my basement, which is about 1200 sq ft with standard 6-inch walls, double-pane windows, and located in a fairly humid area. Even with the heat pump running and keeping the basement around 22°C, it still feels damp at times, especially in the corners and near the laundry area. I’m looking for a dehumidifier that can handle this space efficiently without making too much noise or constantly needing emptying.
Has anyone had experience pairing a heat pump with a basement dehumidifier? Are there particular brands or models that really hold up in a humid basement over time? Any tips for setup to make it work best with the heat pump would also be super helpful. Thanks!
Hi! I have a Senville Leto (18k) single zone mini-split, self-installed about two years ago. No issues.
I’d like to replace our indoor unit with a floor-mount. (Our ceilings are cove and the head placement is low. It has always bothered us.)
There is no Leto floor option. There IS, however, an 18k Aura floor unit available. Is it possible to use the Aura with our Leto condenser?
I contacted Senville and they gave me the expected boilerplate “these are different product lines” response.
Looking at the outdoor units and their specifications, however, they seem nearly identical. I know the latest Aura outdoor units come charged with R454 instead of R410, so the Aura indoor unit would be designed for R454. Maybe that’s a dealbreaker?
I’m sure I’m missing some other differences?
If anyone knows these units well and can offer some advice, I’d really appreciate it. Thanks!
Is there a trick to opening this unit. I bought the house with it installed and want to inspect the coils for cleaning ETC. Bottom screw comes off and I would think it should lift up and out. Is there another screw or does the top cover need to be removed? I dont want to use too much force if im missing something obvious.
TIA
I've had my heat pump running now for about five months and these are the run times/cycles. It works out about two hours per run time, is that right? I have it running at 21 when occupied 5-9am and 3-9pm Monday to Friday with a 19 degree setback and then all day Saturday and Sunday. Hot water follows the same time as I only have 150 litre so needs to recharge after usage (all degrees)
Its running UFH throughout, upstairs and down with only a towel rad jn bathroom. 60s house, no wall insulation but loft conversion with plenty and brand new windows (not sure this is relevant, but reddit suggested adding it)
