You looking to plug it into a standard 10A power point, or have it connected up by an electrician, back to the switchboard.. This will dictate the maximum wattage..

how big is the room?
there is a few calculators around that will give you the wattage required.

room about 29m2, I was looking for a plug in heater, not heat pump...

quick run through on a calc shows roughly 3 kw needed depends on windows and location. if your south of auckland add more kw.
my lounge is similar sized and it has a 5 kw.

so for normal heaters you would need at least two fan/oil/radiant heaters.
1.5 to 2 kw in size. radiant and fan is a bit nicer as it heats whatever its pointed at.
big problem is having power circuits that can handle that load.

Two problems with those systems:

- they can be hacked, quite easily
- If the manufacturer goes bust or gets sick of supporting that model then the "phone home" most have will disable the system.

Both these points are real issues for internet connected things, including cars.

Radiant heaters.... just looking at them going is warming. Oil and fan heaters don't have the same effect.

Something like this panel heater can be wall mounted but you'd need 2400W at least for a large room so it's gonna be more expensive for your tenants as opposed to a heat pump, which is more energy efficient. https://www.trademe.co.nz/home-living/heating-cooling/heater

If its a one level house 2kw might be ok, we have 2 kw gas fire in our upstairs bedroom with is about 45 or more square meters including wir. more than enough, downstairs it takes 20 kw to heat larger than that rooms effectively. In fact we have 9 kw gas, and that is not enough, we need to install an underfloor heatpump ducting system as well. Other lounge is 40 square and has 18 kw wood burner... and its hard to make it too hot...
You have to look at how open the space is and how air is drawn through the house.

Thanks’ I never considered that as I run mine from a Mitsi app on my phone.

I got a heat pump through the government subsided Warmer Home Scheme. Does the job really well but looks really ugly on my 1920,s bungalow wall. Wish I had thought more about what I could have used to be more compatible with the decor....

ahhh... didn't think of the power circuit, good point, thank you! Also, thank you knowledgeable people, as usual TM is a well of wisdom !

thank you for the link, regarding heat pumps in rentals-a whole can of worms with that, including servicing as well as the remote control that can be damaged(some heaters also come with the remote control). Imagine it's lost/broken, the replacement would be hard (expensive) to provide and then there is no guarantee it won't be lost again. Even if it'd be the tenant's responsibility, it's still a hassle. Will look at the panel heaters, thank you!

if its a rental then its required to have a efficient heating which rules out all resistance heaters (panel, radiant, fan, oil etc). land lord will be on the hook for not having it installed. tho i can't remember when the cut off date is for it.

sorry i forgot.

you can get a wall controller for the heat pump, so no remote control required. its hardwired to the heat pump.

I thought the only two requirements is that it had to be wall mounted(not portable) and have a thermostat? As well as to be sufficient covering area. does it say anywhere online that some of the heaters are ruled out? Thank you for the info!

evoalg - 2021-05-29 07:33:00

that's the only info that I have, maybe I should ask in a special thread regarding a heater in rental... the following is from here: https://www.tenancy.govt.nz/healthy-homes/heating-standard/&
quot; Heater(s) must not be an open fire or an unflued combustion heater, e.g. portable LPG bottle heaters. If you use a heat pump or an electric heater as part of your solution to meet the healthy homes heating standard, it must have a thermostat. You can’t use an electric heater (except a heat pump) if the required heating capacity for the main living room is over 2.4 kW, unless you’re ‘topping up’ existing qualifying heating that was installed before 1 July 2019.

In most cases, the acceptable types of heater(s) will be a larger fixed heating device like a heat pump, wood burner, pellet burner or flued gas heater. In some cases, e.g. small apartments, a smaller fixed electric heater may be enough. For more information about different heating options visit the Energy Efficiency and Conservation Authority website. "

Floor mounted ones sometimes look nicer and you can build a "entertainment unit" or some shelves around them.

that says it all.
you need to run the calc to see what size you actually need, but i suspect its going to be well over 2.4kw. hence need a heat pump, or flued gas/wood etc.

An electrician told us the line can handle 10A. A typical heat pump can use it unless you are looking at a 6kW unit when it needs a direct line to the meter.

I don't understand why can't I use TWO heaters if the heating capacity is over 2.4kw? I looked at heaters and two 2000kw heaters(hence giving 4000kw heat) cost 1.5 less than one 2,4 kw one... If both heaters have thermostat, why not? Also, the lounge is kind of strange and it is combined with the kitchen area, but kitchen area shouldn't count?

its basically down to the rules.
if the aera requires over 2.4kw then you need to use heat pump (or fireplace etc)

pretty common to have lounges that combine with kitchens and the area should be included unless it can be sealed off from the lounge (ie close doors). sounds like you have a pretty typical kiwi house.

why the rules don't allow 2x2kw heaters? running costs.
it means tenants power bill will be huge and they probably won't use the heaters and you end up with a damp moldy house.
this is why you need to use heatpumps as they put out 4-5x the heat for the power used.
so your 4kw will only cost what a 1kw resistance heater costs to run. which is a whole lot cheaper, then tenants will probably use it, they will be warm and you get a dry house thats not moldy.

you need to run the calc because what size heater you need depends on what windows, what insulation it has etc. you could need anything from 3kw to 6kw+.
my own is similar size with similar kitchen setup and have a 5kw installed.

tweake - 2021-05-31 20:05:00

And if the tenants have a nice warm house which doesn't cost too much to heat, they will be more likely to stay there for longer, take care of the house and then you have more occupancy.

Happy tenants are more likely to lead to happy landlords.
