buffy has a problem. In Casterton I have a Bosch hydropower instantaneous hot water system. Recently installed. I’d like to make the water hotter, I don’t even need rubber gloves for the washing up. I have the manual. I know what I have to do, I have to adjust the Water Flow Adjustment clockwise. But I’m stumped at the very start because I can’t work out how to take the main cover off. There are a couple of screws which look hopeful down the bottom of the unit at the back.

Does anyone here have this sort of unit? Can anyone tell me if I just loosen them and tip the cover forward? I didn’t try it today because if I mess it up getting a plumber on a Saturday afternoon would be, um, difficult.

I might just have to phone the young man who installed it and ask him.

Oh, it’s an external model.

This one:

Does the manual not tell how to open the access cover?

yes, those screws buffy. loosen, lift and pull towards you.

No, it doesn’t.

Annoying.

Thank you Judge. I’ll do it next time I’m over there.

there should be a couple of pins at the top you have to clear to pull it towards you. or a hook/lip arrangement of some description.

How do I access the water heater controls?
The front cover can be removed by loosening the thumb screws …

The front cover can be removed by loosening the thumb screws (thumb screws are not required to be completely removed). Hold the side of the cabinet and pull forward and slightly down which will disengage the front cover . Once free, hold and support cover and safely remove to a suitable location. To reinstall, locate the top of the cover near the top supporting bracket and slide into position, push back, and locate cut outs on thumb screws. (Require pictures of cover removal)

Ah, OK, so short people like me will have to take the ladder out there.

:)

How did you find that? I’ve just faffed around quite a lot of Bosch sites and couldn’t find it!

lucky search

Actually, I did find some faqs but it wasn’t that lot. There were a lot fewer of them and they didn’t have that answer to what I wanted to know.

Anyway guys, thank you. I’ll attend to it.

if you can reach and support the cover comfortably you shouldn’t need a ladder.

I had to throw my heat pump system away a few months ago

First the fan turned into rust and the capacitor went kaput, then a dire broke out in the control box , I made a repair to the board but given the damage it lasted about a week

I then opted for one of those very water heaters t- Bosch hydro m- thingy

As Morris says loosen screws – I’ m not at home

I can’t see the top, it’s above my head. The unit is fitted to be above flood level. And flood level is around 1m. And I’m not a tall person.

Just bash it with a seldgehammer till it falls off.

You might want to check if the plumber installed a tempering device.

In Qld they’re required by law (I don’t know about other states) and limit your water to 55C. Won’t matter how high you crank your unit as they’re fitted in line.

If I want proper hot water I have to boil the jug.

Peak Warming Man, please advise.

I haven’t fired mine up at the redoubt yet.
Tom the plumber with the brain tumour set it all up. The reason I haven’t fired it up is-:

1. The generator recoil pulled my arm off.
B. A cattle ate the cord off my pump
III. There is not enough water in the tank to commission it properly.

Our 20 y.o. house didn’t have a tempering device until we needed a new HWS (gas).

Now it has one, limiting the water temp to 50 deg C.

That’s hot enough for most household purposes, and yes, we use the electric jug for tea and coffee etc.

“… I ran out of gas. I… I had a flat tire. I didn’t have enough money for cab fare. My tux didn’t come back from the cleaners. An old friend came in from out of town. Someone stole my car. There was an earthquake. A terrible flood. Locusts! IT WASN’T MY FAULT, I SWEAR TO GOD!”

that is a great quote from the BB.

I’ve got a mower with the recoil problem

Son reckons it’s stale fuel, seems to fix the problem as well.

1. The generator recoil pulled my arm off.

maybe give up the CAD and go back to the old set square and pencil, build your muscles up for redoubt living.

Yeah, how you ever going to cock that Browning M2 to keep the zombie hordes away if you don’t HTFU?

>>Son reckons it’s stale fuel, seems to fix the problem as well.

That could very well be the case, J Moi.
It is fuel that has been in the tank for some time.
I’ll try that before buying a new one.
If I break an arm, dislocate a shoulder or lose an eye, I’ll blame your son.

I mentioned yesterday ease it over the compression stroke. Then give it a pull.

Yes. Drain the fuel tank. If you can, put the drained fuel in a clear container and check it. It’s surprising how often you find that water has somehow got into the tank, if it’s been left for a long time.

if you’re going to leave the fuel in it for a while get some of the fuel preserver stuff.

Yes but surley if that was a common problem it would be mentioned somewhere in the destructions.
I’m talking serious and dangerous pullback, when it goes nothing will stop it, it rips the chord out of my hand and slams into the casing.

Listening to BBC2 radio, as i often do.

Graham Norton on now.

Lots of good programmes on during the week.

Lots more on other BBC feeds, like Radio 4, Radio 4 Extra, Radio 5, and even their local radio like BBC Norfolk.

ABC radio often comes close, but the Beeb is still the best at it.

Damn, should have been in ‘Chat’. Sorry.

That’s okay Glowie.

55 would be good. It’s cool enough that I can put my hands under the running tap without adding cold.

Although I wouldn’t mind a remote controlled one, so that on cold rainy nights I don’t have to go outside to start the generator to have a shower.

And that is cheap as chips, probably dodgy brothers.

I think its a massive problem nowadays trying to get something that works

chinese crap forget it unless you only expect it to last one use for anything else buy from somewhere else

Yep. That’s the idea. No scalds.

And no clean dishes either, at the temperature we have at the moment. I doubt we have 55 degrees. I’m pretty sure I wouldn’t be able to put my hands into that without rubber gloves.

I’ve turned into my mother and boil the kettle when I’m washing dishes by hand.

With our water set at 50 deg, it’s hot enough to ‘get your attention’, but not hot enough to cause immediate scalding. You can leave your hand in it for a second or three, with no ill effects, but not indefinitely.

We’ve been boiling the kettle while we had no hot water system. I was hoping to get away from that rigmarole.

but not indefinitely.

still if you did eventually your hand and the water would reach thermal equilibrium. and that wouldn’t hurt.

Get a dish washer

As to your question, this may help:

Check that the water valve is fully open – take the cover off & turn the white knob down the bottom fully anti clockwise. The water valve controls how much water flows through the unit. The more you wind the valve out the more water goes through the hws but the temp of the water goes down. The hws needs a min water flow of 4l per min otherwise it shuts off. So in summer when the water entering the hws is warmer wind the knob out to get the right temp. Then in winter when the water is colder wind the knob in to get the right temp. Also some units have have a gas burner control knob – above the push in buttons & slides left to right. This controls how big the burner flame is – usually low for summer & on full for winter. Give that a try!
