Which combi boiler will provide for simoultaneous running of centralheating, 2 HOT showers and a good pressure (or flow-rate or whatever),dishwasher (cold feed) and washing machine (hot and cold feed).This is not really extreme as it will be found in our house in just a fewyears time as the kids stop having baths and start having showers. Thedishwasher goes on in the early evening, as does the washing machine.Obviously it is difficult to subjectivly define good pressure (or flow-rateor whatever), but I know it when I see it, and I would like to see it it theabove setup! Again, hot is a subjective term, but put it this way, I want tohave to add cold to stop it from being uncomfortably hot when showering.Oh yes, it the showers will also not fluctuate, deviate or perform any otherkind of -ate, when the dishwasher starts rinsing, or the washing machinestarts taking in more water. Or somebody turns on a tap.Now, which combi boiler(s) will do all that.Cheers, Dean.PS, if it had a tap on the side to vend lovely hot tea morning noon andnight, that would clinch the deal!

other appliances calling for hot water. some will even shut off supplyaltogether if the shower is the last on its travels.I personally would keep one of the showers electric, you will be glad , ifthe boiler packs in,at least you will have one way to keep clean .rob

discountedheating -

What, so because they might cost more in a few weeks time that means that the price you pay now, today, isn't real? They've been at this price for at least 6 months.

Have a look at the documentation for the CM67NG RF - Honeywell have taken steps to reduce the impact of RF interference in the new generation by reducing the time taken to transmit from stat to receiver, and by using a 0-100 scale of demand rather than on-off.

With the older model, if the receiver missed a command to turn the boiler off, it would stay on and over heat the house until it regained contact with the stat. Now, if it misses the command, it would stay at (say) 25%, and control the boiler accordingly, until it starts to receive again.

Not a problem. There are at least two sources of service and parts. I also checked the prices of the 6 most expensive items before purchase - I am very careful like that.

Rubbish. It's perfectly viable technology.

Um.. The heat exchanger. The gas valve. The combustion fan. The PCB. The pump. Wonder what the sixth one was - Air Pressure switch, condensate drain trap? Various minor transducers?
