    Shower issue - do I really need to replace my hot cylinder?

    Hi Goldberg. Every possible remedy known to man was used here, including a swap of the valve for another new one. Trevi reps were phoned quite a few times. It seems to be solely due to the new hot feed beginning its journey UPWARDS rather than downwards so leading to insufficient pressure...

    Many thanks to all. A new unvented Santon 210 litre is on order.

    Shower issue - do I really need to replace my hot cylinder?

    Thanks, once again, to everyone who's posted, especially doitall and bathstyle. doitall seems to be sticking with a negative head pump whereas bathstyle, you would still opt for positive but refer to negative as 'belt and braces'. That tells me (and bear in mind I'm no expert) the best...

    Shower issue - do I really need to replace my hot cylinder?

    Many thanks for all the replies. To answer the points raised:- "install the trevi properly then it will work ok." I'm confident that it has been fitted properly bar the layout of the hot feed (should be under the floorboards but that was impracticable.) "The op said the Trevi boost...

    Shower issue - do I really need to replace my hot cylinder?

    Hi. My bungalow has just had an extension added. The builder reckoned that a Trevi Boost shower would be best (a mixer that uses the 'Venturi' principle). Unfortunately, the shower is not hot enough. I now have two different plumbers offering two different solutions:- 1) fit a normal...

    Nice, thanks for that.

    Unvented cylinder - off peak heating.

    I have something similar to Economy 7 whereby overnight rates are cheaper. My vented cylinder has 2 immersions, the top one is NOT at the cheap rate, it's just for 'emergency' use. For reasons I won't bore you with, I may need to change to a pressurised cylinder. I can't be certain from the...

    Replacement of Trevi Boost with a Trevi Therm

    Hi bathstyle. Yes, pump in loft. I'll see if he knows yet what type it's to be and report back. The cold tank sits just a plank's width above the joists. PS Just spoken to my builder. He's spoken to Trevi and the upshot is there could be a problem with air intake as the pump would be too...

    Replacement of Trevi Boost with a Trevi Therm

    Hi all. I've had a 'granny flat' added to my bungalow. My builder, who does his own plumbing, recommended and installed a Trevi Boost shower (it uses the Venturi principle whereby cold pressure 'draws through' the hot water with no need for a pump). Unfortunately, the shower temperature is...

    How to measure Hot Water Head

    I must say, I'm delighted with the way this thread has turned out. I don't understand the half of it but it's exremely entertaining... Aye, it's a one-level house, the HW cylinder is in the airing cupboard. The pipes from it disappear into the loft (where resides the CW tank) and it's in the...

    How to measure Hot Water Head

    I certainly seem to have started something here... You'd said 'head' could be from cylinder to loft pipe, steved101 had it only as far as showerrose. I was just double checking who had it right... All that's in the loft is the cold storage tank. How water cylinder is in the utility room...

    How to measure Hot Water Head

    Thanks, both. The building is all one one level and the Trevi is in the newly built extension. Distance from hot water tank to Trevi is 7 metres. My builder connected the new pipework in the loft space i.e. there's nothing new to be seen by looking at the hot tank, it's all up above. The...

    How to measure Hot Water Head

    Hi. I've just had a Trevi Boost shower fitted and the temperature is very disappointing. I'm going to ask my builder to check it out but I'd like to be a bit more informed before I do so. The instructions contain a graph with Hot Water Temperature on one axis and Hot Water Head on the other...

    Sebo upright vacuum has died...

    I can't imagine vacuums feature much on this type of forum but I'll try my luck. The Sebo I have is an 11 yr old X1. After finishing the hall the other day, I moved to the kitchen and plugged it in. Nothing happened bar the flashing of two red lights - one warns of a clogged/worn roller the...

    Securing a satellite dish to a wood.

    Thanks xerxes. That'll be a screw length of 6 or 7 centimetres then. Can these be screwed straight in or do they require drill-holes/rawl plugs first? Is there any advantage is using a full-thread screw as opposed to the traditional ones which have an unthreaded section at the head? Kind...

    Securing a satellite dish to a wood.

    My apologies for the lameness of this question but I just want to ensure the job is done properly. My new extension is almost complete and it's made of wood (45 x 45 vertical battens securely fixed to studs, with horizontal feather edged boarding). Between two of the battens (and behind the...

    How exactly does my hot water tank work?

    Hello John. You're quite correct about which items appear on each CU. It turns out I was wrong in my idea that the lower of the two switches connected to the tank should be in the 'off' position (as confirmed by Kevin in his reply to my original post). A day with luke warm water proved...

    How exactly does my hot water tank work?

    John, I don't know what to say. Thanks so much for spending all that time on me. This should be my final set of queries though:- So I can press that red button on the meter myself? Is the blue button beside it (marked 'display') a 'stop boost' perchance? Not that I reckon I'll ever need...
