Hot water for bath with no immersion tank?

If I want hot water for my bath I apparently need a pressurised immersion tank because there's no space for a header tank. Is there any electric only or gas (from bottle) solution that would give me instant hot water with enough capacity to fill a bath? Pressurised tanks are not cheap so I might instead have to go with electric shower and small instant electric heater for kitchen and bathroom sinks.

And yes, I know baths are wrong because they consume a lot of power but since I gave up cocaine and high class escorts my bath is my one remaining luxury.

You looked at 'coffin tanks' ?

a gas multi point heater might be the sort of thing?

No mains gas at the house. It's in the countryside. That's why I was wondering if there was a system I could use bottled gas with.

A quick google highlights quite a range of LPG gas powered instant hot water heaters. You'd have to check power ratings and flow rates to see how long you'd have to wait for your bath though....

iirc there are conversion kits for on grid gas boilers and perhaps better if not cheaper made for lpg gas boilers.

You can always use an electric shower to fill the bath, but it is an expensive way of heating water. I agree about baths though; if you get achy they are far better than a shower.

Are they any more expensive than an immersion heater?
I'm not seeing why they should be. Confused

Go back to hookers and cocaine. Much more fun. sean

One of these? Hookers and cocaine and lake optional.

Even more fun in the bath...

Why not a bog standard boiler or combi boiler if you have central heating? Hairyloon

Have you had a second opinion on that?
A header tank need not be a big one...

it does need to be higher than the top of the hot water tank by about a meter so with a squat hot tank and a small header you need at least a 2.5 m ceiling(that rig will probably need a pump to fill the bath in less than a week unless the tanks are upstairs and the bath downstairs.)

header tanks can go on a flat roof if the sides and top are well insulated but they are prone to freezing which is very bad so unless you live in the med or warmer it isnt really an option.

i have used 2 scrap heap challenge ways to have a bath in a wood:

find a suitable spot near a spring so as water can be gravity fed into a bath.

A set a metal bath on rocks ,add a smooth plank to sit on,light fire in a tray and push it underneath.a bit odd and rather too close to the cannibal cook pot for relaxation.it takes a bit of practice to control temp.

B set a bath on rocks,plumb a scrap radiator to plug hole and overflow hole (remember a drain cock ).fill to above overflow. light fire under radiator. convection will drive the hot water out of the overflow and down the plug hole.again it takes a bit of practice to get comfy but tis better than A.

either may require a modesty screen if you have neighbours but sitting in a warm bath with snow falling is rather delightful Laughing

We've been wondering about making a circulation heater for a bath from parts from an old dish washer. As in the pump and heating element.
Anyone tried that? Any comments?
dpack

a dish washer heats a few litres of water in a few mins so it might take quite a long time to heat a bath full.

by the time you have re jigged it all and made sure it is electrically safe it still might not work very well ,it might work but i can think of lots of reasons why something else might be better /safer

i have seen a twin tub used as a water heater for a bath but again tis electric and therefore expensive per bathful compared to gas or a fire

Lightweight. Why not a newton pump in the river? Wink

I fully understand that electricity is definitely not green for heating. I seem to remember that calorie for calorie, if you heat water directly with a fuel and compare that to electricity created by a fuel (as in gas fired power station) then you get about 30% of the heat you would have done if you'd used the gas directly.

However, we've not got main gas. Calor gas is a lot more expensive than mains gas (and I don't want the gas cylinder around either).
This is an indoor bathroom, so fire at the tub - nope. Smile

We have a multi-fuel stove that doesn't heat water. We had a previous bad experience with a rayburn with a back boiler so didn't want to go that way on the hot water. We had too much hot water, even with the fire shut down and ashed over, on a windy night the system would boil and usually about 2am we had to get up to deal with it, having been woken by the thunder of pipes and the fun sound of steam jetting into the header tank.

So our long term plan, is DIY solar hot water. Our short term is having an occasional bath as a treat for sore muscles, with an electric heating system, at least as a top up. Will make a start with heating kettles on the top of the multi-fuel (in winter) and then use the electric shower and then having *something* to finish off, and to keep it warm while soaking. Hence the dishwasher pump idea. Do take on board that it is only for small quantities of water, so maybe not quite so clever after all.

If someone can suggest a heater and circulator that is small, that would be really helpful. Small as in fit under a bath. So can fill the bath with warm water (that may or may not be hot enough) and then top up the heating with a little circulating heater.

if you have a spare chimney or space for a flue would a "copper" such as found in old style scullerys fit the bill?

heat water with a fire and use a small pump to get it to the bath tub

a few examples

i can see no reason such a thing could not even be outside so long as the water pipes are insulated and the pump was a little lower than the pot but indoors.

for diy an oildrum ,a hose to fill it when needed ,some copper pipe and a few fittings to a bath tap and a small pump would be the basic kit ,add a few bricks etc and it could be very cheap to make.

WOW Cool

that is swimming pool size but a similar principle in a rocket stove might be just the thing for a bath
Mutton

Wow on both thanks.

Though on the second one in the barbecue there is the potential for the flame temperature to melt the solder on the pipe joints.

For us - sadly we are in a modern bungalow, timber framed walls, only one chimney - and that is about as far from the bathroom as you can get..........

Hope it helps the OP though.
dpack

so long as there is water in the pipes the solder will not melt even if the water turns to steam ,below about 300c it will stay solid although i would not want superheated steam in my bathroom.
