Hi, I need to sand some flagstones to remove staining on them. So, not too much, but to take the surface off a bit. What would be the best tool for the job and what type or coarseness of sander would I need? Thanks, everyone. Cheers!

bump. Are we all in agreement that this will work out just fine? How often would the joints need to be re-siliconed then? Thanks!

Hi all, We are installing a new wet room and in a couple of places the tiler has left a really tiny margin in the corner where one wall meets the other. By tiny I mean really less than 1mm. There is no way grout would fit in there, but since these joints are usually siliconed, I'm wondering...

Thanks! That's helpful. Is there a downside to this?

I want it to assess how much, how well the controller manages the flow temperature. Worcester can't even provide an estimate of how efficient it it compared to a non-compensating one. Lets say the max flow temp is about 80. I want to know whether this drops down to 50-60 when the temperature...

Hi, thanks for the reply. Unfortunately, I don't think FR110 actually has a heat curve - there is no mentioning of it in any of the manuals, as well as no mentioning of any way of adjusting/correcting the way it controls the heat flow. This is why I'm looking for any info on the heating...

bump?

Has anyone personally installed or has the Worcester FR110 programmable thermostat? This is the Worcester version of the load compensation controller which adjusts the boiler flow temperature depending on the difference between the target and the current house temperature. The less the...

Another question about the heating system setup. This one is regarding a property on the third floor of a tenement. The plumber is suggesting that the drain off for the radiators & pipework be located to the outside on the rear elevation to drain outside off the wall and into the back...

Hi, everyone, I was wondering if someone might be able to comment on whether the following setup would work? Every combi boiler has a minimum required flow rate at which it fires - if the flow is below this number (2.3-2.8 l/min or so) the boiler doesn't fire in order not to overheat...

Thank you, everyone, for the input. Much appreciated. Since it seems borderline impossible to get one controller compatible with Worcester to do the job, do you think it would be possible to wire two separate programmers/thermostats through a junction box to control the boiler by tricking...

I've looked at Honeywell controls, but I don't see any that would offer either weather or load compensation which is what I'm after. Am I missing something?

My understanding is that Viessmann controls will not work with Worcester. And since I cannot change the boiler without a huge expense, that's really not an option. I just find it hard to believe that there is no third party controller that would do a simple thing of getting all the right...

That certainly is the way it looks. Would you mind suggesting any manufacturers you have in mind? Maybe even European, but non-UK ones? Thanks.

should I repeat myself? :D

I never said my house was small... My question is not about whether zoning is pertinent, but about how to control it!

I am trying to find a programmable thermostat control for our heating system which has two zones. The boiler is Worcester Highflow 550CDi. I quite like the FR110 controller with load compensation. But... Worcester says none of their controls are compatible with zones systems. I fail to...

That's correct. Thanks for that. Looks like I'll have to go back and actually find a way to open the boxing...

If this is indeed the cast iron drain pipe, then I guess my question is - does this mean that the tenement's plumbing had been upgraded at some point and the other pipes are also not lead or is it still possible that if I open up the boxing I'll find lead piping? I realize this is a guessing...

Thanks for the reply! I did scratch the surface with my keys - you might be able to make out some scratches in the pictures. I wasn't sure how to read the result - it definitely didn't score easily and wasn't as shiny as I would've expected lead to be.
