1) What’s EndoSan?
EndoSan is a Hydrogen Peroxide stabilised disinfectant with 320ppm silver ion. It’s used to disinfect hot and cold water systems.

  • EndoSan 3 has 3% hydrogen peroxide and is for public and private homes.
  • EndoSan 5 has 5% hydrogen peroxide and is for spas and swimming pools.
  • EndoSan 20 has 20% hydrogen peroxide and is for industries and larger organisations. Protective clothing, gloves and goggle should be worn when using 20.
  • EndoSan 50 has 50% hydrogen peroxide and is a stronger, constant dose version of 20. Protective clothing, gloves, goggles, face shield, vapour concentration gas mask with B filter should be work when using 50.

2) How does EndoSan work?
Hydrogen Peroxide on its own is a poor disinfectant because bacteria can neutralise it. The additional ionic silver present in EndoSan, attaches itself to the bacteria and does two things: 1) it stops the bacteria from neutralising the Hydrogen Peroxide and, 2) it allows the Hydrogen Peroxide to enter the bacteria and kill it.

3) Does EndoSan damage water systems?
No. EndoSan, for domestic water systems, has no corrosive effect. EndoSan 50 has been constantly used in hospitals and airports, for example, for over ten consecutive years and has minimal corrosive effect. This means, it’s never caused damage resulting in any action being required.

4) How much EndoSan do I need?
The amount of EndoSan needed depends on the volume of water being treated… and on the strength of EndoSan being used. The EndoSan Help Sheets tell you everything you need to know.

5) Is EndoSan safe to be in drinking water?
Generally, cold water storage tanks shouldn’t supply drinking water in buildings, so disinfection using EndoSan is perfectly safe. If some outlets are classed as drinking water then, once the disinfection process is complete and the water is back to running clean and clear, the water is safe to drink.

6) What can EndoSan be used to disinfect?
EndoSan disinfects any building’s water system and associates parts – pipework, water tanks, showers.

7) Is EndoSan compatible with Glycol?
No. We recommend that you don’t use EndoSan with Glycol. When using EndoSan as a disinfectant, alternative corrosion protectors are…

8) Can I use EndoSan to disinfect shower heads?
Yes. For soft water areas, see Help Sheet ??. And for hard water areas, see Help Sheet ??.


1) What’s EndoTherm?
EndoTherm is a liquid additive for water-based central heating systems. By allowing water to heat up quicker and stay hot longer; EndoTherm saves an average of 15% on annual heating bills.

2) How much EndoTherm do I need to use?
12 or less single radiators = 1 bottle of EndoTherm
13-24 single radiators = 2 bottles
25-36 single radiators = 3 bottles
37-48 single radiators = 4 bottles
49-60 single radiators = 5 bottles

If you’re unsure, the experts from EndoEnterprises will help you calculate exactly how much you need. They’re also happy to offer advice on how best to use EndoTherm.

3) How does EndoTherm work?
You’ll like this… it’s very clever. EndoTherm changes the properties of the water and makes it wetter! What this means is that it increases the contact with, and the conductivity between the water and the internal surface of the pipes and radiators. This allows the water to heat up quicker and stay hot longer.

4) How much money can EndoTherm save me?
It varies of course, but the average annual saving on heating bills, is 15%. EndoTherm works by allowing water to heat up quicker and stay hot longer. Although EndoTherm works in ‘clean’ or ‘dirty’ systems, it’s recommended that systems are flushed before installing EndoTherm. This will maximise your energy savings.

5) Does EndoTherm work in any heating system?
EndoTherm can be used in any heating system where a boiler heats the water.

6) How long does EndoTherm last?
EndoTherm will stay in closed central heating systems, without any deterioration of energy savings, for at least ?? years.

7) How do I install EndoTherm?
Here’s a downloadable Help Sheet that tells you exactly how to install EndoTherm.

8) Does EndoTherm damage heating systems?
No. Extensive independent tests prove that EndoTherm has no corrosive or damaging effect on any part of any heating system.

9) Can EndoTherm work in conjunction with a corrosion inhibitor?
Yes. EndoTherm actually compliments inhibitor products.

10) Is EndoTherm dangerous?
No. EndoTherm’s classified as a mild irritant, meaning it carries no hazardous threat.

Designa Bug

1) How does Designa Bug work?
Designa Bug does two things simultaneously: it binds odour-causing compounds, stopping them from becoming vapours and dispersing into the air. And it expels microbes which consume the odour-causing compounds, converting them back into carbon dioxide and water.

2) What materials can I use Designa Bug on?
Hard or porous – it works on anything.
It’s proved its worth in the smelliest of places worldwide… pubs and clubs in Scotland, carpets in pet-loving homes, toilets and drains in UK Councils and even underpasses in the Netherlands!
