During the ongoing problems we have been left with no hot water over different periods of time, but certainly in excess of six weeks and the heating has either not worked or been insufficient to keep the property warm all over the last winter. So far this winter it hasn't been too bad because the weather hasn't been particularly cold.
On several occasions the agents contractors have made a recommendation to the landlord to replace the hot water cylinder which he still hasn't done.
The boiler will not heat the water unless the central heating is on constantly.
I contacted the agents several months ago notifying them that I intended to arrange a repair myself and deduct the cost from the rent and they emailed me threatening breach of contract.
I have over 10 emails between myself, the agents and the landlord about this.
I am going through my emails to the agents, there are actually around 30 of them.
The heating has not worked properly since first reported in April 2012.
It is a large house and the system has two boilers, one boiler has not worked correctly and for several months at all since it was first reported. As a result we have not had sufficient heating over the winter period of 2012, and 2013.
The issue with the hot water was first reported to the agents in January 2013, again on 16/02/13 and they then got us some hot water.
The problem returned early 2014 and again it was several months before we got hot water.
I need to go through all of my emails to get firm periods and dates.
Yes it has been intermittent since it was first reported.
The question about the increased gas use was because in order for us to get hot water we have to leave the central heating on constantly as the boiler will not heat the hot water only. As an example if we want to ensure we have hot water when we get up in the morning the central heating has to be left on all night. This has been the case for over 12 months
One boiler is working but it doesn't provide enough power to comfortably heat the house.
