THE heating system at Maidstone Hospital in Kent is set to be replaced to reduce maintenance costs and save energy. Maidstone and Tunbridge Wells NHS Trust has already installed six EasiHeat steam-to-water plate heat exchangers (PHEs) in various extensions around the hospital and now plans to replace the conventional calorifiers in the main building with two 1000kW EasiHeat systems. Larry David, mechanical engineer at the trust, said: "I'm confident the EasiHeats are up to the job because the ones we've already got have given us no cause for concern. For us, the main benefit is that they remove the necessity to strip down the calorifiers every two years for insurance inspections. We're also hoping to save some energy because PHEs are highly efficient."
