Santon Premier Plus - user tips

[onlymechris]

We have just moved into a 4 bed new build with a Santon Premier Plus 300l unvented system. Having been used to a combi boiler we have really no idea how to use this system effectively especially as the tank is far too big for our current needs!

I was hoping someone could comment on how long the tank will stay hot for after say 2hrs of heating? Ie. could we shower at say 10pm when it was on from 4-6pm? (note, we basically have two showers a day and abit of washing up and that's it really)

There are only two of us living here at present so dont really want to be over heating the tank unecesarily.

Any tips would be most appreciated as there is no user manual provided and very little on the itnernet.

thanks in advance,

Chris

These are very well insulated and I've seen them retain heat over a w/end to still give HW on Monday. What litre capacity is it?

it's a 300l tank I believe.

Do you use more energy heating up a cold tank than keeping an already hot tank hot? Ie. if the tank remains hot for some time then surely I would be better off perhaps only having it on once a day rather than twice?

Excuse my ignorance to all this but this is really not my cup of tea

300 litre is for large family multi bathroom use. Assume it's heated indirectly by a CH boiler. Keeping it permanently on is wasteful if you only use a small amount. However you shouldn't let it run out cold. Best way is work out what you need am/pm and heat it to 60-65C prior to the relevant usage time.
