I can’t see why one would buy Chinese heater not CE marked and with slightly thinner materials to produce at a certain price point IE cheap when the difference for a Planar is only a few hundred. Considering the amount that is spent on boats is all other areas and the potential risk, must be a false economy.

Oh but I can buy 5 for the price of 1, 5 of what? Buy cheap buy twice

Supposing you do not have that only "only a few hundred. " ?
A 2K Planar is over £500.00 if you add P&P. Until very recently the Chinaspacher could be bought for around £100.00.
As for buying twice, yet to hear of any of the knock offs,even after many years of use, being consigned to the scrap bin.
In fact, a few folks who did go to the extreme of buying two just in case, still have them lying around unopened in their original boxes.
On the Planar website the exhaust in the kit looks remarkably like the dodgy chinese version with the spot welds around the seam ?

Just out of interest, what are you paying for electricity (per unit) and heating oil or diesel (whichever is cheapest) where you live?

According to Google there’s 8 kWh per litre of fuel in a 5kw diesel heater - so in the UK it’s currently cheaper to get heat from a diesel heater than from an electric heater, if my maths is correct.

It may sound strange .... but no-one knows what Electric costs today or tomorrow here .... price is changing hour by hour....

The only way to try and have some sense is to set a fixed monthly fee and hope year end does not have too high a 'debt'.

I currently pay 400 euros a month ... but in 2020 / first half 2021 - I was paying 190 euros per month.
I now get a 30 euros per month from Govt as 'help' for electric.

Diesel is currently about 1.80 euros per Ltr here ...... if you want supply for domestic heating - you need register and then you receive a subsidised volume only .... what price I have no idea.

Is that 120mins max time in your Eber manual? I don't recall reading it in mine.

Www.solocoastalsailing.co.uk
On my timer. If you set it running manually it will run until battery goes flat or fuel runs out.
The default setting on my timer is for 120 mins.
I think you can change these in the service settings to a maximum of 12 hours. I would have to RTFM to confirm. Butler technic have the manuals to download for each of the eber timer controls if you want confirm.

This is EXACTLY the argument presented by European Shipbuilders against Asian Shipbuilders ...

Basically post war UK / Euro Shipbuilders were building to scantlings + a few % ........

Korea as one of the first - built to the exact scantlings ..... Japan and China soon followed suit ....

The only difference today ... shipbuilding to the threads Diesel Heaters ??

Open up your expensive Euro unit and see what's inside ..........

No longer are Euro items adding that % ... they are competing on terms of Customs duties / time of delivery ..... and so often using same Chinese produced parts

Can you utilise the existing webastard harness and heating controls?

I spent today final fault finding.

A well respected local marine electrician hadn't wired up our eber to a remote thermostat correctly. ?

The grey and red wire to the burner wasn't connected in parrallel with the positive to the remote thermostat. Indication of a remote sensor fault and no modulation of burner by remote.

I get nice and toastie much quicker now as the burner gives max output until within 2 degrees of set temperature. My D4 was acting like a D2!

Blatantly robbed from another but I have corrected Stu's maths!

Thinking on the other day as it got colder and watching my smart meter ratchet up!

A 2kw electric heater uses 2kw per hour at circa 35p a kwhr so 70p/kwhr

My old 24 kw gas combo boiler costs 1.50 per hour to run but heats the whole house

A 5kw spacher uses 0.5 ltrs of fuel an hour, 28 sec oil is about a quid a ltr, so 10p/kwhr.

Is the spacher now a viable domestic heater alternative for spot areas?

My daughter has just had a discounted Kerosene delivery for her oil heating. I hope she won't miss a few litres every time I visit?

The Chinese are certainly capable of building to extremely high standards, but that doesn't change the fact that by far the majority of what they currently flog us is cheap tat with v poor quality control, v poor documentation and spares back up, and sometimes fraudulent claims of CE etc marking, branding, build standards, etc.

For some things I'm willing to accept poor quality because of the price point, for others I'm definitely not.

Don't get me wrong .... I agree. My post was to illustrate the fact that Far Eastern construction kept to the scantlings - unlike Western practice up till then

There are many videos where people have ran a 5kw on one litre and they all use 0.4l/h which is what the instructions claim.

Some of the China heaters now come with pretty comprehensive books A4 books full of instructions.
I fully read the marine instalation instructions for for mikuni, eber and webasto before fitting my Chinese one. You can download them as a pdf.
I've seen a few people using them for house heating and nicely fitted outside in a box. Another friend uses an all in one to heat his workshop.
The big question would have to be "would you buy another Chinese heater" I'm sure the answer from users would be a very high percentage Yes...

The one I recently bought came with CE / UKSA mark, a readable booklet, and seems decent quality. Was £95 but now has increased and is out of stock, but this looks to be a good one.

I took the duff Eber D4 out this morning and this one fitted exactly into its place. The outlet connection was slightly smaller so I simply swapped the end cowl from the Eber which fitted precisely. The exhaust was an exact fit. The original air inlet hose was knackered, so I used the one supplied, but they are both short hoses with a simple air strainer anyway.

I wonder if the Eber tick tick pump would work, but for now I'm planning to use the supplied pump & tank and run it on kerosene.

I've connected the power, but need to splice the controller to the cable to the Eber controller.

Which one did you buy ?
Went for this in the end.

12V Air diesel Heater LCD Display For Trucks MotorHomes Boat Bus Car 5KW | eBay

and have been recommended to use

Truck, Boat & Marine Heaters, Service Kits and Parts

To upgrade bits so that it is suitable for marine use.

There is a whole planet of geeky YouTubers doing all sorts of stuff with them. Lots of information about aftermarket control panels, piping and tanks. My current thinking is I'll run this off a seperate tank and not use the engine one.
