X Pot

[Scotty]

Biomass service company are trying to get me to install a filter called an xpot compact ? they recon its going to help long-term with the corrosion of the boiler. The sample they showed me was like coke a cola but this was taken from the bottom of my buffer tank .
I just don't get the filtering . The filter is just a 1/2 inch pipe T 'd into the main 2 inch pipe and doesn't have any positive flow through it and apparently uses "side filtering".
Its 2.5k to fit.
anyone put one in? thoughts please?

Ring the manufacturer and ask them, then ask them if treatment of the water with softener will be better. If you are in a hard water (lime scale/magnesium) area you may only need to treat the water with softener. Then price up both options. Sounds like snake oil to me.

I think you need to have some sort of performance guarantee, however are you softening water to reduce lime scaling, or getting rid of gunge that will corrode and block the system ?

Systems I’ve been around have the pots installed at install.
Softener reduces corrosion with an inhibitor combined around the hx

you do get quite a bit of metal filings running around the system, so a large magnetic filter might be better. if you have ever stripped down a failed wilo pump you usually find the rotor covered with filings due to it is a permanent magnet surrounded by boiler water.

Best thing I’ve ever put in to keep our heating system in tip top condition.
They’re not cheap to run at the start to get it to the right condition then it’s preventative maintenance

As I put in my profile I was in the Water Treatment Industry for approx 12 years - so am aware of this x-pot system.

The X-Pot is a side-stream filtration system that is designed to be fitted onto domestic heating systems in large scale buildings/houses to treat the water that goes through a chilled or heating closed system (your radiators/heating).

It is sold by a company called Vexo International - http://www.vexoint.com/contact/
The xpot filter takes out particulates in the water, along with any by-products of corrosion (iron, hence the magnet) from the inside of the pipes or radiators - this stops sludge build up and improves the efficiency of the heating systems - they are cracking for this purpose.

If you're having issues with corrosion from the water within your boiler, then the xpot wont help or stop this - you will need a chemical water treatment process to control the chemical properties of the water.
Corrosion in Boiler system is primarily due to dissolved oxygen in the water.

Adding a softener will help with reducing scaling in the system/boiler. As with every ~1mm of scale deposited in the system will reduce the heat efficiency of the system by approx 10% - so costing you a lot more money to heat the water and help the best heat-exchange out of the water.
