We live in a black of flats run by a Large Social Housing Association and we have Pulsacoil Boilers have been blowing up which just over five years old.

We told that a small water tanker above the boiler (like a small toilet system)

We told we are suppose to fill the water tank with water but to no inlet pipe into the system.

Is not this a Health and Safety issue

The water tank on the top is header tank.  It should be open at the top, just get a jug of water and pour it in.

PulsaCoils are thermal stores, rather than hot water cylinders. Like conventional hot water cylinders, a thermal store is a container filled with hot water but here the similarity ends. Once filled, the water in a thermal store never changes. Instead, the heat stored in it is used to heat the tap water using a heat exchanger. This allows the hot tap water to be delivered at full mains pressure, and is one of the primary benefits of installing a thermal store instead of a conventional hot water cylinder.
Common problems - depleted water in the thermal store.

Original PulsaCoils have a top-up cistern built into the top of them. This may or may not have a float valve connected to the mains water supply to fill it. When there is NO mains connection, there is usually provision for manual filling by the user by means of a tap on the wall nearby. Not good if you are not active!  When the user doesn't realise this, water lost from the thermal store through evaporation and/or leaks can prevent the PulsaCoil from working. If the water level falls too low, the heat exchanger coil ceases to be immersed in stored hot water so when a hot tap is turned on, and the unit will not deliver hot water. The problem is progressive. As the water level reduces, so does the hot water performance. The answer is to check the water level in the top-up cistern and top it up to the waterline embossed into the wall of the cistern.

Hi guys

I don't have marks on the cistern. But it sounds like mine may be too empty. Can anyone tell me how much water you need?

My cistern setup:

1. I have the ballcock setup thing but it's not working when I press the ball down. So I guess IF it requires filling up, it will be manual.

2. Then there is a pipe going through the lid of the cistern that stops in midair on the inside (probably 3 inches into the cistern. Should this pipe be emersed? This can't be an overflow pipe to the outside world as it bends above the cistern. I dont' know if the heater puts water in the cistern from above or if it sucks the water from the cistern with this.

3. There's also a pipe (out, I assume) at the bottom of the cistern)

Symptoms: There's some lukewarm water in the cistern even though tap water is ice cold. The red light is flashing. When switch off the mains power, press the thermostat reset button and switch on the power, the system runs (maybe noisily) for about 4 mins before stoppign and going red light flashing.

I dont want to sound obvious, but why dont you call your landlords repairs line?

why spout off (no pun intended) on an internet forum about it being a H&S hazard, have you even reported the repair?? you must've spent more effort posting this than just picking up the phone and asking the people responsible for fixing it.

sheesh!

We now demand that a professional come from Gledhill which we all need a transparent water tank with a press button to fill the tank when water running out.

The professional come from Gledhill and done a health check and most was filled with wrong parts not the manufacturer recommend part

We stil having problems not enough hot water but we having a presentation from them next week.

  • From Nic Bliss, 22/05/2012 9:28 am in Resident-led Scrutiny Reports

    There is not a right or wrong way to do Resident Scrutiny Reports.  The key issue is what will best lead to outcomes that bring improvements for tenants and prospective tenants.  If a key reason to involve tenants in involvement activities, including scrutiny exercises, is so that they can constructively challenge how the landlord operates so that services, value for money or other aspects of the business can be improved, then not allowing tenants to raise the points they wish to raise would seem to be counter productive and not using the potential business advantages that tenant involvement can ...

  • From Will Nixon, 17/05/2012 6:17 pm in What defines a 'living' room

    The crux of the issue is whether the property is deemed to be "more extensive" than required and the criteria will be contained in the Landlord's own policies and procedures.

  • From Shaun Aldis, 17/05/2012 11:13 am in Repairs ban

    There are a few factors to consider, which are dependent upon what is in the tenancy agreement by type of tenancy i.e. social landlord or private lease. Normally the landlord is responsible for repairs unless stated otherwise and they should be carried out within a reasonable period of time, however again unless stated there are no fixed time limits, and the length of time considered to be reasonable would depend on the type and severity of the repair.  Most landlords will normally undertake repairs once they have been notified about them, however if they refuse or fail to do ...

  • From Paul Jones, 16/05/2012 11:04 pm in Tenancy status and mutual exchanges.

    Those with lifetime (periodic) tenacies swapping with another person with the same will still swap using a "Deed of Assignment" and take over eachother's tenancies, not begin new tenancies.  BUT, if fixed-term or "affordable rent" is involved on either side, new tenancies are started. I have studied the Localism Bill and this is what it says.

  • From Blair Mcpherson, 16/05/2012 1:01 pm in Why be a tweet

    I have recently joined twitter. I was initially reluctant but my son was very enthusiastic saying it was better than Facebook because it was easier to use, wasn't restricted to your " friends" and the limit on characters keeps comments short and to the point. For me twitting is a way to promote my articles and books to let others who share my interests know what is influencing me and to pick up on what others in my areas of interest are talking about. Of course I am not immune to the temptation to follow the trend.

  • From Shaun Aldis, 16/05/2012 12:54 pm in Fire risk or not?

    Where there's any question about the performance of a product, I would suggest that it's important to get the products in question back to the manufacturer or importer, for them to inspect them and advise you as to the cause of the damage. This response can then guide and feed into your risk analysis. This should be channeled through your product supplier, be that a wholesaler, distributor, or trade supplier. My experience of this is that the quality of manufacturers responses will be improved if details about the installed conditions, fault levels, cable run distance, Amperage/kW loading, and nature ...
