Steve,

The plumbers modified the domestic water to pressurised on the last visit and I had assumed the central heating/ heat pump was also changed over. Currently I'm struggling to work out where the air might be coming from as a fair amount has been vented. I might have to venture into the attic space shortly.

Regards

so you have no f&e tank? my old stanard pumps on full pelt were causing suction, probably due to my diy plumbing but all maybe due to hight of house, when pump was on if you open bleed valve in atic bedrooms no water came out, so changed to some bargain modulating pumps at 59 and never had issue since, i already had the autovents but they may have added to the issue with old pump, no air no noise no probs now.

Steve,

Things are getting back to normal now so my focus is moving elsewhere and something a little less high tech, roof repairs. Having removed the sandstone ridge tile (which split!!!!!!) I could get on with replacing slates:-



One day I'll be too old to be working off roof ladders............

Regards

they hang roof tiles here!! no nails in the top, we have s/s hooks that support the slate at the bottom they hook over the laths, very fast and seems to last.
have you got a slate scissors just got some and they are also brilliant, made here in france but very expensive here, cheaper of amazon by far.

another funny thing here, no roof ladders, i spent ages trying to find some, they make their own on site out of cobbled together lath, then drop them in the gutters which are put up with this in mind.

Steve,

I know the regular slaters around here use slaters axe's but there is a local guy who produces a guillotine type device which I use. It can only be used on the ground due to its size but is very effective.

I now use Hall hooks for slating repairs or copper tingles depending on circumstances. The former must be somewhat like the hooks you describe. Had to break out a 'new' ridge tile. I then mixed up a full 25kg bag of non-hydraulic lime mortar to finish the job and used the 'spare' to fill in gaps in the steading wall.

Previous repairs to the property have been done in sand/ cement but I now use lime.

Regards

Steve +1 for the scissors so easy to use.
Even an idiot like me can do a good job. Worth the money I bought half shares in a pair with a chum who also had a roof to do.
Amazing the uses that left over hooks can be used.

Good Evening All,

My ongoing struggle with SSE over FIT payments goes on. The readings I submitted prior to going away in early July were entered in to my 'old' account apparently so having harassed them with my latest readings I see I now have a pending payment to my bank account - hooray.

It's now 10 months since the heat pump and all associated paraphernalia was installed and the savings from this and other 'rationalisations' are becoming clearer.

We were paying a total of circa 323 a month for energy 18 months ago and this is now down to circa 142 a month. This is a combination of the efficiency of the heat pump over the LPG condensing boiler, replacing the old 9.5kW electric shower with a 'conventional' one driven by hot water produced by the heat pump, reducing the battery charging for the standby generator from 24hrs to Economy 7 charging only, one of the bigger savings has been reducing the excessive usage of the 300W/ hr electric airer from 24hrs a day to Economy 7 usage only (currently actually off completely).

It also includes the fact that the heat pump and Immersun are making more use of the electricity produced on site.

As noted elsewhere SSE will allow me to expand my system but I'm struggling to see the economic sense in doing so. I'll need to see if I can have a sensible dialogue with them as my planned expansion will need to be larger than planned to make it 'viable'.

We have lost energy over the last two months with the solar thermal system being 'airlocked'.

Regards

Good Morning All,

It's a sure sign that autumn is its way as the mice are back!! That's several been zapped by the electronic mouse traps. It has also 'forced' me to get on with properly blocking the old cat flap hole which is the number one easiest route in for them along with the exhaust hole for the old Stanley range, the fibreglass has had its day.

Aided by Kate we are now going around finding all the 'drafts'. Having been here 17 years I have finally put draft strips on the bottom of the Utility Room doors.

I have still to fit the whizzo vent flap to the kitchen extractor.



I've also been playing with the heat pump settings. It has been running on the default 'heating' curve since installation whereby it is expecting to need the radiators at 50 degrees C for an outside temperature of -5 degrees C. I have progressively bought this down to a 42 degree setting. The internal temperatures are being maintained and, more importantly, we have reduced the heat pump short cycling. I've incorporated a before and after photo now I've found one showing the short cycling.





The big spikes are for the hot water.

The installers have been in to refill the Solar ET loop which did cure the problem but only short term as it is back to where it was. I see from reading another thread it could be the expansion vessel which is at fault. I need to chase them again.

Regards

Richard

I had the temperature at the top and bottom of my wood burner showing 888 degrees C on Sunday morning, found the 2 cables eaten through, repaired them, then less than 12 hrs later they had been eaten through again!!

Ah yes, autumn and mice. My back door opens at ground level with no step, so from this time on I have to make sure I shut the door promptly. If I leave it open longer than a few seconds, the little devils all rush in as a gang, then I have to spend the next 4 hours baiting then emptying the mousetrap. I now have one of those ultrasonic rodent deterrent things plugged in in the kitchen that hopefully will do it's job, so that I won't need to leave a trap down.

I had an early version of the electronic deterrent  and when I was moving house I found a mouse's nest underneath.  Are the newer ones any better?

My wife gets annoyed if we leave a door open for few seconds and get some flies in as a result. Despite being in the country, we haven't seen any signs of mice. I don't know why?

Tinbum,

Now I've blocked up the old catflap and the old Stanley vent hole and got all three electronic mouse traps up and running we've had no mice caught for two days and no sound of them gnawing the Celotex in the kitchen roof space.

I now need to complete the hole to install a permanent hatch for any future mouse invasion. This hatch will also allow me to insert more fibreglass above the 50mm Celotex, more as a 'draught limiter' than for its thermal properties.

Currently on with some very overdue draught tracing. All the big obvious ones have been eliminated but it is clear from when the Shower Room fan goes on that there is a draft coming in from under the door despite the Velux window being open.

I have recently instigated timer switches on both routers and switched off everything in the Living Room which was on 'standby' only.

I now need to get back to the solar tracker which is currently performing irregularly............

Regards

Richard

I'm at 10 mice and counting in the last 3 weeks, now employed a second mouse trap  fingers crossed!
