Sorry to trouble you with what is probably a naive question but I am a complete Combi bolier virgin. Since moving out of my parents home 17 years ago I have had a traditional oil bolier with a hot water tank and in our new home we have taken the plunge when we needed to re-plumb and installed a combi boiler.
So far the boiler has been installed (Baxi Duo Tec 40 HE), I have TRV's on all rads, new pipes and new rads throughout the house. I am about to get a wireless thermostat installed (Honeywell 927). The boiler controls are obviously pretty simple (on/off, water temp contol and heating temp control) but I am keen to understand how the system actually works.
At the moment as it is mild (and we have not actually moved in) I have set the boiler temp to about 25 degrees and have set the TRV's in the various rooms to 1 or 2 throughout the house, hot water temp is right down to just above luke warm as we are not really needing hot water. It is keeping the house from getting cold but if you were sitting watching TV you would want it warmer (but as I am frantically decorating it is grand).
Query:
1. The heating temp range on the boiler goes from 25 to 80 degree C according to the manual but what level should I set the boiler to in order to get it right when we actually move in?
2. If the boiler range is 25 - 80 degree C does the boiler kick in if the temp it reads at the boiler is less than 25 degrees and as I dont have a wireless stat to override does that mean that probably at the moment my boiler (which as mentioned is positioned in the garage) is going to be kicking in all the time as the external air temp is about 11 degrees currently.
3. Is the way I have the system currently set up correct in order to keep the energy costs down at the moment but prevent the house from getting very cold (house temp appears fine at moment).
4. If I turn the boiler temp right down to lowest setting will it kick in at 5 degrees and if so is this due to a frost stat in the actual boiler identifying the surrounding temperature? Given the fact my boiler is in the garage which will be colder than the inside of the house is this likely to kick in a lot over winter & if so does it just take the bolier to +5 degrees or to the temp set on the boiler?
5. Is about 19 degrees for the heat and about 50 degrees for the hot water a reasonable boiler setting when we are moved in and use the TRV's & wireless room stat to control rooms.
After installing the wireless thermostat I have a couple of queries:
1. Say I want the temp of a our living room to be set at 20 degrees what temp setting to I set the boiler to in order to ensure that it achieves that or does it not matter and I can set it at the lowest temp as the wireless stat will override it anyhow?
2. Has anyone a view on whether hot water should be set to its highest temp the boiler can go or the highest temp that you actually use the water at e.g the temperature that we would normally use for a hot bath or hot water for dishes. Is it just a waste to run the water warmer than that and does it affect flow rate?
Sorry for the barrage of questions and I hope some kind soul can take pity on me and answer them. Many thanks in advance.
