When it comes to heat recovery, good installation is the key to getting it right, says EnviroVent. Even the most energy efficient appliance will fail to perform if it has been poorly fitted, it explains.<br> <br> EnviroVent has developed the energiSava 380, a whole house heat recovery system, designed as an easy one-man installation. This lightweight and compact system has been developed in a modular format which allows it to fit through a standard loft hatch. In addition, this unit incorporates simple pushbutton commissioning – making life easier for the installer, EnviroVent says.<br> <br> The energiSava 380 can also be rotated to enable both right and left configurations depending on the type of installation required. EnviroVent claims that the system also performs to the highest efficiency on SAP Appendix Q, achieving a low Specific Fan Power (SPF) of 0.40 W/l/s and thermal efficiency of 93%.<br> <a href="http://www.envirovent.com"><br> www.envirovent.com</a>
