Nu-Heat Water Cylinder

[john f]

Hi All
I have underfloor heating system with rads upstairs run off a 210 L Energy Master2 Cylinder
The system was designed by Nu- Heat and was installed as per spec
The system has run for 3-4 years and has been most effective
However I think the cylinder is leaking I noticed a small plastic cap on top of the cylinder insulation cover had popped off and was wet
Today I noticed a small damp patch on the concrete at the bottom of the cylinder and I can smell the fernox
The unit is cylindrical with a flat top and bottom
I imagine the inner cylinder is leaking into the insulation ?
I called Nu-heat and because I have not had the anual service on the cylinder the manufacturer will not cover the unit
Therefore I will have to pay about £1000 plus installation costs
or will it be something less sinister (hoping !)
I havn'nt noticed any pressure loss over the two days though

Any Comments would be much appreciated

Think you are jumping to conclusions thinking you need a new unit,do not think this is the case,you have saved fours years service charges,time now to spend on one and hopefully should can be able to be repaired at the same time.. with an extra charge ofcourse

Thank you for the reply
I,m afraid being a domestic property I didnt know I had to have it serviced I have always had the boiler serviced each year
However The unit has never been over 1.5 Bar and it has a 3 bar relief valve and a vent on the top all supplied by Nu-Heat so how could it fail with all of these safety measures
Nu- Heat say they will not help as they need service history but I can not find anything in my paperwork that insists on yearly tests
I will ask them to provide the paperwork supplied and addressed to me stating this service is required

funny that, I do boiler services and some customers want their cyls all checked annually others think your taking the mick, so you cant win. However being that most things that fail are easily resolved I wonder if the annual service is worthwhile in monetary terms? some may feel not

Oh !!

I think I may book my regular 4 year service
By the way there is no leak this morning and pressure has remained
I,m wondering if the cat had visited

Thanks

I have found the fault !
As mentioned earlier, I in fact was jumping to conclusions
I had a leak from the spindle of a motorized valve that was dripping on top of the cylinder and running through a little plastic plug on the top that wasn't fully seated which in turn ran to the bottom of the cylinder
