Its a 2007 build so this has been done already.Cavity wall insulation?
Sure - but I need to improve on what i've got - and its not going to be good enough as we move into the not so distant future. Most semis built around this time will be all virtually the same format - cavity insulation, attic insulation, floor insulation (hopefully...have no way of checking this now!) - executed to varying degrees of competence ie. may not be even application of cavity fill, some houses more airtight than others, etc.It depends on how well the house was constructed in the first place
Its not bad on irish 'standards' given that its part of a development build. However, that doesn't mean that it can't be improved upon and that its of a standard that would be acceptable in countries that take a more progressive stance re. quality of build relative to energy efficiency.A 2007 should have a high level already
Something I have given some thought to previously. However, if I was to do this, I wouldn't have too much confidence in getting a result out of the builders in putting it right (if found to be substandard) as company is now defunct.as you know builders have their own ideas on quality control! If you want to improve your insulation it may be worth while getting it checked for air tightness and with a thermal camera to find thermal bridgeing/their mistakes..
Many of the BER assessors can offer these services. In particular, the blower door test - as I believe that is often carried out on new builds for a more accurate assessment. Otherwise, a google search will throw up service providers.Where do you get a blower test and a thermal camera. Whats the cost?
Sure - but its an irrelevance to me - as even if i could prove that they werent, i dont see much hope of getting this rectified - so i'm not going to expend energy on it.I wouldn't assume Irish standards for 2007 were adhered to.
Yes, have had it in mind to get these too - but your suggestion got me thinking I will go for Honeywell wireless TRV/Room Stats as mentioned [broken link removed] - instead of just a couple of zonal stats. This should lead to efficient use of heat and the stats are relatively cheap.Herbie said:Thermostatic radiator valves?
Have not spent much time investigating this option - so thanks for the suggestion. The little i do know is that ground source heat pumps are cost prohibitive between the capital cost and the ongoing electricity requirement. I'm not really familiar with air source heat pumps. How disruptive was it to retrofit??moloney2 said:Our house was built in 2004 and is 1200 sq feet.We have added an air-source heat pump which works down to approx. 1 degree and then the oil burner kicks in at temp.s below this
That doesn't sound too bad.At the moment for sept to nov it worked out at 1 euro per day for heat and hot water
What is the cover made from? So as a result the unit doesn't ice up nor does the unit expend any energy in the process of keeping it ice free?we built a simple cover for it with vents for the intake and outake.
I have mailed them so should know more when they get back to work.I believe that the company Wharf plumbing can be quite helpful and answer any questions that you might have,
Thanks for posting this quentin as had not come across this point in the other threads I read. I know they have a trial in place at the moment but is there any firm timetable for its introduction?I would caution one thing about the system you are proposing. Wholesale electricity prices (the price paid to the generators) can be as high as 25c per KwHr during the peak time around 5.00pm. Smart metering is ultimately going to result in a multi-tiered price structure for electricity which could see retail electricity prices of 40c to 50c at peak times to dissuade use.
Don't have the space for it unless it could be buried! The other point of frustration is that even if this could be utilised as the ideal workaround, they (esb) still charge a fee for nightrate that cancels out the benefit. Surely a little rational thought would lead them to the conclusion that they would get more even distribution of useage (together with greater takeup of these technologies) if they axed this charge?the best option would be a two tonne buffer tank to ensure that all electricity used can be off-peak - if you have space for it.
