Combi 4 E boiler - winter heating

M, yes you can upgrade but you need a new PCB (to interpret the new functions) as well as the CP Plus control panel....so won't be cheap

however, advantages include setting the fan speed to high or low, rather than the unit deciding....you can get much more out of the heater by setting it to high, even when on electric 1 (900w)...

..you can also prioritise heat over water (or vice versa) by selecting boost...

to find the 'cool air' setting, both heating and hot water MUST be in the off position (I fell for this one....) and then the option 'vent' appears which can then be controlled by the fan....between 1 and 10 I think.

so, yes, it's less confusing to use and has quite a bit more flexibility.

oh, and although it's iNet compatible, Truma will want to sell you another bit of kit to 'complete the interface'....

needless to say, I didn't bother...

just to add to TG's informative post, when on gas only (off grid camping) you will just use the leisure battery for the fan....this should no ok for a few days, but if you're going to be doing this a lot, I would seriously look at two or three things......

firstly a solar panel (80/100/120 watt) to constantly top up the leisure (and vehicle) battery and secondly perhaps a 2nd leisure battery to increase time off grid.... the by product is that the SP will keep all batteries well charged while van is t being used....immobilisers and alarms can be a drain.

also, if off gridding, you'll use more gas (especially in winter) and Calor refill aren't cheap...a refillable system from Gaslow/Gasit etc will allow purchase of LPG at around 25% the cost of bottled gas.....additionally, if you decide to tour abroad, the refillable system can be used all over Europe (with an adaptor or two) whereas bottles can't be exchanged.

again, good luck with the van. 

And of course is another plus over the Aldi system 

Thanks. Is there a selector switch or is it automatic? If there is a switch, I can't see it!

had to cast my mind back a bit but here goes.....

the first picture is the power selection switch....to select midxed mode you need either the bottom setting (gas + electric II, 1800w) or one up from there (gas + electric I, 900w).

whats confusing is that, on this dial, Truma use the flame symbol for 'gas' whereas in the other picture (the function dial) the flame signal means 'heat' (whatever the power choice) ...

So, to use heat but no water, it's the one down from the 'O'.

Yes, I heard about the refilllable system - we’ll see how it goes but might be worth investing in it for our European trip next year...

Thanks for your upgrade reply ''BB' 👍

I looked into doing this but came to the same conclusion, I think we got to about £600 by the time labour was added! An easy way to tell what boiler you have is apparently the colour! If it has a grey cover it is expensive to upgrade but if its all black it only needs the programmer display panel, still probably not cheap. Looking forward to having the fully programmable version in our new motorhome.

We like it David much better than in the SE, I take it you won't have Alde in the new MH then.

TG

No we don't, that is reserved for the Autograph range. We have ordered one of the new Alliance range the 66-2.

Thanks all for your helpful responses!
