The Scope Of Work Includes: The Subject Of The Order Includes The Modernization Of The Existing Boiler Room Located In A Multi-Family Residential Building At Ul. Policzańska 42 (Case No. 3107) In Płock. The Source Of Heat For Heating And Hot Water Preparation Is A Viessman Paromat Simplex Boiler With A Power Of 225 Kw (Burner Power 150 Kw) Fired With Biomass. The Main Goal Of The Modernization Is To Solve The Problem Of Obtaining The Standard Temperature Of Hot Utility Water Supplied To The Building At Policzańska 42A. The Modernization Of The Boiler Room Includes The Installation Of Three Heat Pumps With A Capacity Of 16 Kw Each. The Automation Will Control The Operation Of The Pumps Depending On The Domestic Hot Water Temperature. Located In A Buffer With A Capacity Of 300 L. The Heating Medium From The Buffer Will Heat Domestic Hot Water. In Three Existing Capacitive Hot Water Exchangers. It Was Assumed That The Heat Pumps Will Operate Up To An External Temperature Of -5 O C. Below The Above-Mentioned Temperature, Domestic Hot Water Will Be Heated By The Existing Paromat Simplex Boiler. Central Heating Installation - Separate Systems Were Designed For Each Building, Equipped With Circulation Pumps And Three-Way Valves. The Technological Installation Of The Boiler Room Is Subject To Replacement. The New Installation Should Be Made In Accordance With The Design - E.G. From Kan-Therm Steel Pipes In A Pressed System. Each Circuit Will Be Equipped With Individual Heat Meters. Central Heating Installation Will Be Filled By A Water Softening Station, E.G. Syr 3200.
