Hi Dave
Would you be kind enough to answer a question related to having the pump situated after the heater; it's been on my mind all day.
Have you specifically configured the two in any particular way to facilitate the heating and pumping process, or does the average pump have the ability to suck the water through the water heater wherever it is placed?

Long Story - ready?
Back in the early days I decided to buy a Fogwash - basically the same as yours but with a flue. I connected it all up with the pump before the heater. At that time I also had a Gardiners Claber reel, they were great - cheap as chips and really lightweight. Around the same time Gardiners brought out some new hose I can't remember much about it but it wasn't microbore as we know it but some quite thin walled stuff I also had a crappy Varistream digital controller. These factors added together were a disaster waiting to happen (although I didn't know it at the time).
First job I ever did with hot water and the thin walled hose expanded with the heat - so much that it jammed the reel and crushed the core, the problem being that the dead end setting on the controller didn't pick up that the hose was growing and wouldn't shut the pump down.
New hose and new reel and off I went again, backed the pressure down on the calibration and started work of course now the heater wouldn't fire up because the DE kept shutting the pump off ::)roll Re-callibrate and off we go ....................
Same thing happened - the hose started to expand - unfortunately you can't alter the pressure with a digital controller without it being switched on which meant by the time I managed to faff about with it the reel was wrecked (that's two now in two days). Whilst all this was going on the pressure relief valve under the boiler blew and squirted water out of the bottom.
I thought the problem lay with the controller and bought another ........ exactly the same.
It dawned on me that all this pressure inside a boiler probably wasn't a good idea :o So I changed it around.
I now have a metal reel, proper hose, analogue controller and no trouble at all!
And hardly ever use the heater ::)roll

Nice one!

I'll show you mine if you show me yours.

Ooh Err!
Should be a couple on here somewhere but I can't find 'em May have to wait 'till tomorrow.

Cool!

I never knew this.............
In my van it would be much easier to have the pump after the heater. I just presumed hot water was bad for the shurflow pumps?
-
I use to use an indirect calorifier tank for heating my water and found shurflo pumps couldn't handle the hot water as I would get a maximum of 6 months use out of them before they played up giving me lots of trouble. I switched from them to Flojet pumps and they all lasted at least 3 years each.

Here you go Mr Thompson - I am aware that the pump is upside down but it doesn't bother me.(http://www.cleanitup.co.uk/smf/1418563548_H4.jpg)(http://www.cleanitup.co.uk/smf/1418563560_H2.jpg)(http://www.cleanitup.co.uk/smf/1418563573_H1.jpg)

God knows why my pictures turn around when posting!
Anyway, the hot hose from boiler to pump is braided stainless flexible hose the kind you'd use in your bathroom.
The hose from filter to boiler is a cold water washing machine fitment.
Hose from pump to reel is hot water hose (red) that came from ebay for caravans and motorhomes.
Steel quick release fittings are brill and come from Gardiners
Had to source a couple of brass fittings for the Flojet pump (male to male) Shurflow I had before is different.
Brass elbow on the reel.
Two marks on the flow adjuster tell me where the heater fires up normally with my set up. In the summer I usually open the valve fully and run it as a cold system.
Hose reel is the metal cloverleaf with a couple of rods through it to stop the sides bowing with hose expansion.
Gas cylinder is double strapped up against the cage with gas bottle holders for motorhome.
Airvent was sourced from internet and cost about £30 I think, flexible hose from B&Q

You need to search for the specs for the pump - they will handle fairly hot temps - just took me ages to find it. Been set up like this for about four years I think, can't remember for sure.

Nice set up.
I like the vent!
Do you have any links to it and was it easy to fit?
-
Dead easy if you're happy to chop through your roof!

Yeah that worries me a tad. Lol
Where did you get the vent from?

Somewhere in the uk can't remember now. http://www.amazon.co.uk/Broan-nautilus-Roof-Vent-Cap-RVK1A/dp/B000LDBKIW

I think the company that sold the Broan vent here in the UK doesn't exist any longer/no longer has an internet presence. You may have to get it from the USA.
They make different sizes - you need the 4" one.
They are quite simple so they could be fabricated out of stainless steel if you can tigweld.

If you look on the spec sheet you will find the dimensions.
