Product Spotlight: HTH Easiflo 10 First
The HTH Easiflo 10 First is an automatic chlorine doser designed for small commercial swimming pools up to 150m³. Unlike manual chlorine addition, which can lead to peaks and troughs in sanitiser levels, the Easiflo 10 First delivers a steady, controlled release of chlorine directly into the circulation system.
It uses specially formulated HTH slow-dissolving chlorine sticks, allowing chlorine to be introduced gradually as water flows through the unit. The result is more stable water quality, reduced operator workload, and improved swimmer comfort.
Because it operates without electricity, the Easiflo 10 First is ideal for facilities looking for a dependable, low-maintenance dosing solution. It’s commonly installed in hotel pools, therapy pools, holiday lets, and communal residential pools throughout the UK.
How the Easiflo 10 First Works
The Easiflo 10 First is designed to be straightforward, robust, and easy to manage. Here’s how it fits into your pool system:
Step 1: Inline Installation
The unit is installed directly into the pool’s circulation line, typically after the filter. As water flows through the Easiflo chamber, it passes over the chlorine sticks inside.
Step 2: Controlled Chlorine Release
As water moves through the unit, chlorine is released gradually from the sticks. The dosing rate can be adjusted to suit pool volume, bather load, and operating hours.
Step 3: Continuous Disinfection
Because the Easiflo operates whenever the circulation system is running, it helps maintain consistent free chlorine levels throughout the day — reducing the risk of under- or over-dosing.
Step 4: Simple Refilling
When chlorine levels drop, operators simply open the unit and replace the sticks. No measuring, no pouring, and no electrical components to maintain.
Personal Experience: Why Automatic Dosing Makes a Difference
I’ve worked with many small commercial pool operators over the years, and one issue comes up time and time again — inconsistent water quality caused by manual chlorine dosing.
One client was managing a small hotel pool and relying entirely on hand dosing. Chlorine levels were fine in the morning but often dropped during peak usage. After installing an HTH Easiflo 10 First, the difference was immediate. Chlorine readings stabilised, combined chlorine issues reduced, and daily chemical checks became far quicker.
What stood out most was reliability. With no electrics and very few moving parts, the Easiflo 10 First just works. For smaller commercial pools, that simplicity is a major advantage.
Summary and Recommendations
