Well done Andy and thank you for taking time out of your day to bring us the videos, we certainly appreciate it. The switch module is a great little investment, and yep, your two for two. My current heater that I’m using and which failed to work with the switch module is the Hcalory 6-8.5Kw, the big heater. With my heater, when you cut the power the controller just switches off and the heater just slowly stops working with no cool down period. I purchased the heater at the beginning of the summer 2023 so it would be interesting to read in the comments if anyone else has the same heater and has come across the same issue when using the switch module. Thanks again Andy….Keep warm!

thank you my friend xxxx

Does the module come back on just as it had been, or does it basically reboot? Looks like a reboot to me. Can you confirm it came back on as it had been set? One thing I notice is that my power transformer has about a one-second delay once power is pulled, so perhaps the controller doesn't lose power so long that it fully reboots?

[@andyfireblade]

this works really well. yes its almost seamless. although i have heard if you wire a battery in parallel and set the transformer to 13.8v it will keep the battery charged and change automatically. thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy

Hi Andy, Firstly, I love the time and effort you put into these videos. If this device works for you, that's great. My concern is that if the PSU or the plug top fuse fails there is no visual/audible that the device has switched, then later the battery voltage will drop. (a lot of these heaters will detect low supply voltage and self power down using the cooling cycle. Just a thought.

[@andyfireblade]

Thanks for the tips!

Nice one Andy, I've got a few of the heaters all running on kerosene. I recently built a box for one to be placed outside and found that with the heater inside the box I ran the exhaust a good length inside the box before exiting at the furthest point. With the box being well vented some of the heat from the exhaust got recirculated into the house increasing heat output, totally by accident but think its worth some thought.

[@andyfireblade]

good idea, thanks for sharing cheers andy

[@SteveEvidence]

Great. Thanks!

[@techtinkerin]

Good suggestion I might have to set this up, currently running on xbox supply and have not yet added anything for power cuts. 👍🙂

[@andyfireblade]

great cheers andy

[@GRILL332]

Ok Andy, I watched your entire series and subscribed. Please do a summary video of everything you learned. You moved the home unit outside, you went back to a short exhaust, etc. Why? Can the heater preform ok long term with the long exhaust, etc?

[@andyfireblade]

thats great , thanks. i have tried lots of different things. i have a few heaters on the go. this red one is pumping heat into my home right now. I have learned that if you extend the exhaust, you need to use a wider pipe to allow the gases to flow better, ideally within reason. or the heater can " soot up" you can also adjust the fuel to allow for this. Have you got a similar setup? cheers andy

The burner works best with 13 V, so it is necessary to add a charge maintainer,,,

[@kan815k]

Its a good project, BUT how often there is a power cuts are in UK ? Module also top up the battery when not in use?

[@andyfireblade]

true, we are lucky. we dont have many here. i dont know if it tops up the battery. thanks for looking cheers andy

[@Sirtomalot-c5s]

It doesn’t just have to be power cuts, with today’s regulations we can see fuses being more sensitive in households that will trip the power if a device or similar becomes faulty in a house.

[@bill2960]

Hi interesting project. Is the power supply not having a adjustment. Pot on it so you could just set output voltage at 13.8 volts wire it directly to battery and also to heater if the mains fails it will run on the battery with no interruption when power comes back on the battery will recharge. As well as run the heater. And at 13.8 volts the battery will be happy. As that is about the float voltage.

[@andyfireblade]

i will do this! thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy

[@martinbrammer3857]

Hi Andy, I keep meaning to ask - great videos & tests etc btw - but what did you use to get a tidy (if it is a tidy) hole through the house/brickwork to feed the hot air pipe through? Cheers!

[@andyfireblade]

hello martin, thanks. i used a core hole drill on a electric drill. amzn.to/3O9ISa5 cheers andy

[@Sirtomalot-c5s]

This device is a great investment for these heaters so please keep in mind it doesn’t just have to be power cuts to be concerned about. With today’s regulations we can see fuses being more sensitive in households that will trip the power if a device or similar becomes faulty in a house.

Thanks for sharing

[@stevin707]

Just ordered a heater and im curious, why is it so important to have a backup power supply? If you didnt have the backup power during a power cut what would happen to the heater?

[@andyfireblade]

hey Stephen, when you turn off the heater, it doesn't go off for a minute. it goes through a cool down cycle. this is so that the circuit board doesn't melt. it doesn't always happen, its people being over cautious. thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy

[@rolandwakeman3391]

Hi Andy can you please let me know if it changes the battery when it’s being used. Regards RW

[@andyfireblade]

no it doesent thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy

[@OnlyKnowsGod]

I don't think it works as in the previous video. It was set on 2 where the default is 3. But when he switched it of mains it jumped to 3. To me what likely happened is it switched of for a millisecond and thus came on.

[@decalshedsignsco6849]

what about keeping the charge fully loaded in battery? what would happen if thepower goes off with the heater? it did happen me once but it just went again after.

[@andyfireblade]

thank you for your comment . yes i agree, some people say that the heaters are ok after a power cut? did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy

[@OnlyKnowsGod]

A second is an eternity in electronics, the flickering was likely the electronic brain resetting and switching back on. It likely realised that it had a power fluctuation and kept on running. This is not an ideal safety device a uninterruptible power supply needs to switch in under a microsecond or less to not interrupt any digital device let alone the microcontroller on the heater.

thank you for your comment did you see my other heater vids, www.youtube.com/@andyfireblade let me know what you think, cheers andy

[@gazbullen]

please be careful these are only 10amp rated the heater can draw 12amp+ on start up

[@andyfireblade]

thank you my friend, yes i didnt expect it to work. cheers andy

[@techtinkerin]

On shutdown they draw max too as it relights glow plug. I suppose as a backup for power outs it's okay.

[@fulldraws]

I did see that Amazon did have 12 amps availble @@techtinkerin
