Recommended for houses up to 7500 sqft (700 sqm)
The Hydroflow HS40 is the domestic model designed for the larger family home up to 650 sq m (7000 sq ft). Fitting one HS40 protects the hot water tank, pipes, pumps, and appliances from lime scale build-up and removes existing lime scale too. The HS40 fits around the pipe, is suitable for all types of pipe material, and works independent of flow rate. The strength of the signal is 100% more than the HS38.
The unit can be fitted around pipes of up to 63mm (2.5")diameter and of any material with no plumbing required.
