Boiler flo

Silverbird65

We have Worcester Bosch condensing boiler. Had it on 65° not heating house it takes hours for the room temp to reach 18 from 13°. So switched boiler up to 70° sadly it won't be great for economy. I am OAP and not in great health so what can I do? Any suggestions. I think being warm is so important 
Thanks

Put another jumper on?

A lot depends on the make up of the house and the type, a four bedroom (relatively modern) house with cavity insulation, loft insulation and double glazing will warm up quicker than an old Victorian house with single glazing, and high ceilings that loses heat like its going out of fashion.

Don't let the house get so cold. 13C is cold and the fabric of the house will take a long time to warm back up. Keep it at 15-18C

Thanks for the advice we have a 2bed end terrace with cavity wall and log insulation. The temp drops quite quickly from 28 when heating off in this very cold weather.

The higher the temperature the quicker the loss, but 28 seems a bit too high to be honest, try turning it down to something more reasonable like 20c.

We do allow the temperature over night to drop to 14c, but it comes on an hour before we get up to allow the fabric of the building to get to 15-16c during the day and 17-18c during the evening.

Leave the heating on for longer.  At a lower temperature, the boiler will be using less gas than if it was running at full blast.

A 5 degree difference is a lot and will require a high (inefficient) flow temperature.

You'll be a lot more comfortable setting your heating to 17C/19C and once the house is warmed through, you'll be able to reduce your flow temperature for maximum efficiency. You'll need to allow a few days before consumption figures settle down and you can make a judgement.

I assume your house is at 18 before going to bed, I suggest you don't let it go off at bedtime but to reduce the setting to 16 deg. Yes, it will fire now and again through the night to hold 16 deg but won't have to work hard the following day to reach 18 deg. Mine is a worcester bosch ...63 deg flow temp. See here I wrote on a different posting:

The weather has been consistent the last few days to do a test.... 0 deg. Our normally goes off at 9pm to 9am but have tried not switching it off but reducing through the night to 18 degrees so not working so hard the following day to get the temperature up, it would be normally be16 deg at 9am..........  The result: On for 12 hours, 20/21 deg cost me £2.55 (65kw/h). On for 24 hours 20/21 but 18 through the night... cost me £2.61 (66kw/h)  I have done this test other years with similar results. So for me/us at home near enough 24/7 running the c/h for 24/7 is a yes. The extra cost in elec' was negligable.

@silverbird65 Good info given above. In the meantime i would get a convector heater while you work it all out for main room.  13 degrees is miserable and not good.
My new boiler isnt warming living room but am working on it.
Can have this second source of heating and put it on ver low in main room.

Why would you use a convector in place of mains gas CH; it costs 350% more to run?
OP, set the heating at a sensible level to keep you warm, your health is more important than a higher gas bill. As an OAP you are getting at least £1,050 of energy bill support this winter, and possibly as much as £1,250 if you are on benefits/disabled. That should cover any extra expenditure adequately.
